查看使用 Room Persistence Library 创建的数据库的内容

Question

Is there any easier way to see the contents of database created with Room Persistence Library in Android Studio?

Answer 1

In older Android Studio versions:

Emulator -> Android Studio -> Device File Explorer -> /data/data/{$packageId}/databases/ -> Save As -> https://sqlitebrowser.org/

In later Android Studio versions (3.5+):

View -> Tool Windows -> Device File Explorer -> /data/data/{$packageId}/databases/ -> Save As -> https://sqlitebrowser.org/

Answer 2

in android studio 3.1.*

in tool window bar click on " Device File explorer " generally you can find this in bottom right corner of the screenn

open directory in data/data/your-application-package/databases

with new architecture 3 files is created in databases directory

your-database-name
your-database-name-shm
your-database-name-wal

you have to export all 3 in the same directory

then open first one file (that is with your-database-name only ) in any sqlite browser.

and now you can see all your data .......

your-database-name-shm
your-database-name-wal

these two extra files are needed to open db file if you will open database file only, than you will not found any table in that file

Answer 3

Method 1

You can use Android-Debug-Database , and you can CRUD of your data from a browser, and then you can see your Preference data from a browser.

Method 2

If you don't want to use from Browser and you have to check other files,need to check your data changes, use a Genymotion Emulator.So you have to root your emulator.Try to Root your emulator, plz see in https://stackoverflow.com/a/44039429/2772552 . Let me know if you are not OK.

Download & Install DB Browser for SQLite

In Android Studio versions >= 3.0:

Open Device File Explorer via:

View > Tool Windows > Device File Explorer

In "Device File Explorer" Go to:

data > data > PACKAGE_NAME > databases

where PACKAGE_NAME is the name of your package (it is com.edgedevstudio.sample in the example below)

Right click on the database and select Save As. Save it anywhere you want on your PC.

Open, DB Browser for SQLite & click 'open Database' and open the database.

In the case of the example above, you should locate " todolist " NOT "todolist-shm" nor "todolist-wal"

If you do not export the 3 database files (db_name, db_name-shm & db_name-wal, where db_name = name of the database) you will not be able to read the database.

Personally i use Android Debug Database

Android Debug Database is a powerful library for debugging databases and shared preferences in Android applications.

Quick start

Add this to your app's build.gradle

debugImplementation 'com.amitshekhar.android:debug-db:1.0.4'

Just start the application, you will see in the logcat an entry like follows :

D/DebugDB: Open http://192.168.1.104:8080 in your browser

With the latest release of the Android Studio 4.1 Canary , Android Studio provide new tool called Database Inspector .

You can use this Database Inspector tool to view the database file and it's content, you can also edit database content.

If you are using Room Persistence then it also provide facility to run @Query with in the Android Studio. You can see the run button of the left side of the @Query annotation.

If you are using LiveData then it will live reflect database content changes,

With Android Studio 4.1 Canary 6 and higher, you can inspect, query, and modify your app's databases using the new Database Inspector. For example, you can debug your running app by modifying values in your database and testing those changes on the device.

I recently tried Sethto By Facebook .

Stetho is a sophisticated debug bridge for Android applications. When enabled, developers have access to the Chrome Developer Tools feature natively part of the Chrome desktop browser

You just need to include it's gradle dependency and call in MainApp. That's it. You get access to all the tools in chrome window by using chrome://inspect/ including your sqlite database.

Following is a screenshot where inspected by Room Database on Emulator. I only tried in emulator so far.

Best and easy to view, edit, add & delete your roomdatabase in debug mode in android studio.

Implement dependency in build.gradle

debugImplementation 'com.amitshekhar.android:debug-db:1.0.6'

Copy paste below code in your activity

public static void showDebugDBAddressLog() {
    if (BuildConfig.DEBUG) {
        try {
            Class<?> debugDB = Class.forName("com.amitshekhar.DebugDB");
            Method getAddressLog = debugDB.getMethod("getAddressLog");
            Object value = getAddressLog.invoke(null);
            Log.d("link", "showDebugDBAddressLogToast: "+(String) value);
        } catch (Exception ignore) {

        }
    }
}

Call Activity in oncreate.

showDebugDBAddressLog();

Add permission in AndroidManifest.xml

<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>

Run The app in dubug mode

Search in logcat

link

You see the link in logcat

showDebugDBAddressLog: Open http://192.168.1.100:8080 in your browser
