Android Debug Database is a powerful library for debugging databases and shared preferences in Android applications
Android Debug Database allows you to view databases and shared preferences directly in your browser in a very simple way
- See all the databases.
- See all the data in the shared preferences used in your application.
- Run any sql query on the given database to update and delete your data.
- Directly edit the database values.
- Directly edit the shared preferences.
- Directly add a row in the database.
- Directly add a key-value in the shared preferences.
- Delete database rows and shared preferences.
- Search in your data.
- Sort data.
- Download database.
- Debug Room inMemory database.

Add this in your settings.gradle:
maven { url 'https://jitpack.io' }If you are using settings.gradle.kts, add the following:
maven { setUrl("https://jitpack.io") }Add this in your build.gradle
debugImplementation 'com.github.amitshekhariitbhu.Android-Debug-Database:debug-db:1.0.7'If you are using build.gradle.kts, add the following:
debugImplementation("com.github.amitshekhariitbhu.Android-Debug-Database:debug-db:1.0.7")Using the Android Debug Database with encrypted database
Add this in your build.gradle
debugImplementation 'com.github.amitshekhariitbhu.Android-Debug-Database:debug-db-encrypt:1.0.7'If you are using build.gradle.kts, add the following:
debugImplementation("com.github.amitshekhariitbhu.Android-Debug-Database:debug-db-encrypt:1.0.7")And to provide the password for the DB, you should add this in the Gradle: DB_PASSWORD_{VARIABLE}, if for example, PERSON is the database name: DB_PASSWORD_PERSON
debug {
resValue("string", "DB_PASSWORD_PERSON", "password")
}Use debugImplementation so that it will only compile in your debug build and not in your release build.
That’s all, just start the application, you will see in the logcat an entry like follows :
-
D/DebugDB: Open http://XXX.XXX.X.XXX:8080 in your browser
-
You can also always get the debug address url from your code by calling the method
DebugDB.getAddressLog();
Now open the provided link in your browser.
Important:
- Your Android phone and laptop should be connected to the same Network (Wifi or LAN).
- If you are using it over usb, run
adb forward tcp:8080 tcp:8080
Note : If you want use different port other than 8080. In the app build.gradle file under buildTypes do the following change
debug {
resValue("string", "PORT_NUMBER", "8081")
}You will see something like this :
- Android Default Emulator: Run the command in the terminal -
adb forward tcp:8080 tcp:8080and open http://localhost:8080 - Genymotion Emulator: Enable bridge from configure virtual device (option available in genymotion)
As this library is auto-initialize, if you want to get the address log, add the following method and call (we have to do like this to avoid build error in release build as this library will not be included in the release build) using reflection.
public static void showDebugDBAddressLogToast(Context context) {
if (BuildConfig.DEBUG) {
try {
Class<?> debugDB = Class.forName("com.amitshekhar.DebugDB");
Method getAddressLog = debugDB.getMethod("getAddressLog");
Object value = getAddressLog.invoke(null);
Toast.makeText(context, (String) value, Toast.LENGTH_LONG).show();
} catch (Exception ignore) {
}
}
}As this library is auto-initialize, if you want to debug custom database files, add the following method and call
public static void setCustomDatabaseFiles(Context context) {
if (BuildConfig.DEBUG) {
try {
Class<?> debugDB = Class.forName("com.amitshekhar.DebugDB");
Class[] argTypes = new Class[]{HashMap.class};
Method setCustomDatabaseFiles = debugDB.getMethod("setCustomDatabaseFiles", argTypes);
HashMap<String, Pair<File, String>> customDatabaseFiles = new HashMap<>();
// set your custom database files
customDatabaseFiles.put(ExtTestDBHelper.DATABASE_NAME,
new Pair<>(new File(context.getFilesDir() + "/" + ExtTestDBHelper.DIR_NAME +
"/" + ExtTestDBHelper.DATABASE_NAME), ""));
setCustomDatabaseFiles.invoke(null, customDatabaseFiles);
} catch (Exception ignore) {
}
}
}As this library is auto-initialize, if you want to debug inMemory Room databases, add the following method and call
public static void setInMemoryRoomDatabases(SupportSQLiteDatabase... database) {
if (BuildConfig.DEBUG) {
try {
Class<?> debugDB = Class.forName("com.amitshekhar.DebugDB");
Class[] argTypes = new Class[]{HashMap.class};
HashMap<String, SupportSQLiteDatabase> inMemoryDatabases = new HashMap<>();
// set your inMemory databases
inMemoryDatabases.put("InMemoryOne.db", database[0]);
Method setRoomInMemoryDatabase = debugDB.getMethod("setInMemoryRoomDatabases", argTypes);
setRoomInMemoryDatabase.invoke(null, inMemoryDatabases);
} catch (Exception ignore) {
}
}
