android-debug-database's Issues

Can I use this lib to view a db file?

As title says, can I use this lib to view a db file?

Can you add the feature to open encrypted database

Hi, I have an encrypted sqlcipher database. I can hardly see anything right now. Can you please add a feature to manually decrypt the database?

stetho vs android debug database

how is this different then Stetho ? http://facebook.github.io/stetho/

gradle version is too high.

This is a very practical projects, but I think the gradle compiled version is too high, lead to low version of the project can't compatible.

So if it can in low version?

I can see the datas in the browser of my phone, but can not in my computer

I can see the datas in the browser of my phone, but can not in my computer. with the same url.

is any trouble with my wifi? I use the company's wifi

If there is a subdirectory in /data/data/myapp/databases, than it doesn't work

It just throw an exception like this :

E/SQLiteLog: (14) cannot open file at line 30058 of [9491ba7d73]
E/SQLiteLog: (14) os_unix.c:30058: (21) open(/data/data/myapp/databases/cc) -
E/SQLiteConnection: DB info: sqlite3_open_v2, path: /data/data/myapp/databases/cc, flag: 6, ret: 14
E/SQLiteConnection: DB info: errno = 21, errno message = Is a directory
E/SQLiteDatabase: Failed to open database '/data/data/myapp/databases/cc'.

Although I can open the web, it only show databases's name, you can't see the data.
It seems the lib deals with dir as a database, and cause everything broken after.

No data shown on the panel and Exception

I have a problem with showing the data of the emulator.

I was following those steps:

• i added the dependency
• i made this: adb forward tcp:8080 tcp:8080 in my terminal
• after that i was able to see the panel at: http://localhost:8080

But when i go to this address it shows just nothing, but a blank panel with no data:

I also get this Exception:
java.lang.NullPointerException: Attempt to invoke virtual method 'android.database.Cursor android.database.sqlite.SQLiteDatabase.rawQuery(java.lang.String, java.lang.String[])' on a null object reference 07-30 00:31:54.978 16077-16159/com.okset.realmsample W/System.err: at com.amitshekhar.utils.DatabaseHelper.getTableData(DatabaseHelper.java:83) 07-30 00:31:54.979 16077-16159/com.okset.realmsample W/System.err: at com.amitshekhar.server.RequestHandler.executeQueryAndGetResponse(RequestHandler.java:235) 07-30 00:31:54.979 16077-16159/com.okset.realmsample W/System.err: at com.amitshekhar.server.RequestHandler.handle(RequestHandler.java:118) 07-30 00:31:54.979 16077-16159/com.okset.realmsample W/System.err: at com.amitshekhar.server.ClientServer.run(ClientServer.java:78)

Why i cannot see any database?

You should allow people to use a different port than 8080

It's possible that port 8080 might be in use by a different application.

In which case, it'd be better if the user could pass their own port number into the DebugDB#initialize() method.

Database Version

It would be great to have a feature to check the database version (PRAGMA user_version), which could be used in migrations.

i have begin a iOS Debug Database Project

https://github.com/shaojiankui/iOS-Debug-Database
based Android-Debug-Database

Export .db file

Awesome library for unrooted device!

Can we actually export the .db file to somewhere?

Relayout navigation to breadcrumbs UX pattern

Hi Amit,

What you think about changing navigation to breadcrumbs UX pattern (something like [Home] -> [Database] -> [Table] in the top of the screen with popups for database or table selection)?

So it gives more spacing for content of tables with more than several columns (my case :) )

How can I contribute to this repository?

Hi, I am Devendra, a Java Developer and Android Enthusiast, I have used this library in one of my android projects and its great. I want to be part of development. Let me know, how can I do it?

Unable to view database of more then one app?

Hi Amit thanks for such an awesome tool, its really helping. i am developing multiple apps with v 1.0.0, unable to view databases of more then one application.

Use a dynamic layout to avoid horizontal scrolling

The data column should fit the full width.

Right now only about 4-5 columns can be shown and if there are more columns in a table horizontal scrolling is needed although there is plenty of room left.

The simplest solution is to just remove the senseless padding in

Android-Debug-Database/debug-db/src/main/assets/index.html

Line 113 in 2538f9d

<div class="container padding-fifty">

Query results are not displayed in 1.0.1 any more

if you select a table and try to run a custom query like e.g. "SELECT name from SOME_TABLE", no results are shown on the right. In 0.5.0 feature worked. Please fix

Order by with query not working

Hi ,

When I use order by clause it is not showing desired result ,But correct data is shown after UI table column sorting.

Thank you for useful library

Realm support?

Great work on the library!
I was wondering if this library has Realm support? Since, Realm browser app ( where you can see realm database ) is available only on Mac, it would be great to have Realm support for this library.

Cheers

Question: can it handle apps without changing their code?

Integer overflow?

Large INTEGER columns seem to overflow, showing negative number instead of the real value

sqlite> .schema user
CREATE TABLE USER (
id INTEGER PRIMARY KEY AUTOINCREMENT,
createdAt INTEGER NOT NULL,
  ...

Pulling the .db manually and querying

sqlite> select createdAt from user where id=112;
createdAt
1480519860000

DebugDB shows that same cell with value -1243857120

The log info is : D/DebugDB: Open http://0.0.0.0:8080 in your browser

what's worry with me, i can not open the database…

App crashes when I try to load provided URL

Hi,

Saw your post on Medium and thought I would try this out but I am not having much luck. When the app starts up I see the URL but when i try to open, the app crashes and the following error is displayed:

E/AndroidRuntime: FATAL EXCEPTION: Thread-49637 Process: <app.id>, PID: 8713 java.lang.NullPointerException: Attempt to get length of null array at com.amitshekhar.server.ClientServer.getDBList(ClientServer.java:412) at com.amitshekhar.server.ClientServer.handle(ClientServer.java:216) at com.amitshekhar.server.ClientServer.run(ClientServer.java:128) at java.lang.Thread.run(Thread.java:818) E/AbstractTracker: Can't create handler inside thread that has not called Looper.prepare() E/AbstractTracker: mTrackerAsyncQueryHandler is null

Do you know what the error issue might be. Not sure if its related but I am using DBFlow ORM.

[Feature request] Change the number of displayed rows per result page dynamically

The number of displayed rows per page is hard coded to 10 right now. This can be inconvenient, especially when working with large result sets. I would like to be able to change the number of displayed rows dynamically (e.g. with a drop down component like in this DataTables example).

the database can't see after minifyEnabled true

i can open the link in my brower http://xxx.xxx:8081 but the database can't see after minifyEnabled true

How to see shared preferences data

RT

Can not run Android Project because duplicate entry gson.

The log as follows:
Error:Execution failed for task ':transformClassesWithJarMergingForDebug'.

com.android.build.api.transform.TransformException: java.util.zip.ZipException: duplicate entry: com/google/gson/Gson$1.class

It seems can not load any data?

I think this project is great, so I write a test app to see it's feature.
I'm sure my phone and my computer are in the same WIFI.
When open the browser, just like this, it has a welcome button, can't see my DB, what's wrong?

It always open a html which is in my project

There is a html in my project,and then it always go to the html when i try to open the address that printed in the console. I try to change the port,but it does't worked.I am confused.

Library not working if table name is a reserved keyword.

Made a table with name "transaction" in my app, and library crashes when i request that table.

I'd like to fix this bug. Thanks.

it could not work on Emulator,just work on real Phone?

Pragma doesn't work

Hi,

If I try to execute query like PRAGMA table_info(myTable); I'll get error.
Root cause is in DatabaseHelper class in method executeQueryAndGetResponse.
It checks if first word in query is "select" and does query otherwise does execSql which doesn't support results.

I think this could be solved by checking for "pragma" as well and in that case executing "getTableInfo" method.

can't query having '%' string

may be fix javscript code

$.ajax({url: "query?query="+escape(query), success: function(result){

       result = JSON.parse(result);
       inflateData(result);

}});

Error:Conflict with dependency 'com.google.code.gson:gson' in project ':app'. Resolved versions for app (2.8.0) and test app (2.7) differ

Edit and Delete rows have errors

i cannot delete a row.. it shows deleted successfully but when i click again on the table name it shows the deleted row.. when i edited a column value whole table got updated to the new row(redundant rows). help me with this.

[Feature request] Files management

Hey,

great tool! I treat it as a central place to get data from the app during my development. Although it would be nice to have files management as well. Files stored in the application's files directory could be:

• viewable
• deletable
• uploadable

What do you think about it? Do you have any plans? Is this kind of contribution possibly welcome?

display encrypted data

I try to use it, but shows the encrypted data.

Why they cannot communicate by USB？

Your project is great.
But in my work environment ,it is inconvenience to use wifi.
Why they cannot communicate by USB？

ip adress issues

some times receive the Ip is 192.168.199.240, This will not open the database. My local Ip is 192.168.2.xx.

http://0.0.0.0:8080 is shown for real phone

When I use my smart phone as AP and let my laptop connect to it, the link will be http://0.0.0.0:8080 and it cannot show anything.

The simplest solution I found is change the URL to router's ip address, for example, http://192.168.1.1:8080, and then it will work. Can you make the address show in the logcat?

can I see realm database?

do you support other database any kind?

How to set path that database is not under the original path?

may be in storage?

The culprit seems to be the following line.

mDatabaseDir.list() is returning null because

If this abstract pathname does not denote a directory, then this method returns null.

https://docs.oracle.com/javase/7/docs/api/java/io/File.html#list()

Although unlikely to happen (if you're choosing to use this library, you probably already have the database ready), it would be nicer if it could handle the edge-case accordingly.

Does it support SQLCipher based sqlite ?

When i tried, it dint worked.

How can i use this in my project, which is not a Android studio project?

Hi, guys! Please help!
For me, my project is not AS(Android Studio) project and is not complied by gradle. It's an android source code project complied with Android.mk. And I don't have right to update the project to android studio project.
I cloned the code and complied it, now I have debug-db-debug.arr and debug-db-release.aar. I can add aar file into Android.mk as static lib, but what should I do in my java code?
What should I import and how to init DebugDB? port ?

Please help, thanks!

Can't see custom database location?

It seems you take DBs from com.package.packagename/databases/
My DB location is in com.package.packagename/files/myfolder/mydatabase.db .
So, How can I see for custom database. Thanks
