How can I automatically uninstall the app from the emulator after running the Android unit test

Question

I am using Eclipse ADT to test an Android App. However, after I execute the test suite once, the emulator will have the app installed. I need to remove it from the emulator since the test will fail next time if the app is already installed on the emulator (due to some stored data).

I tried to search a way to start a clean emulator every time I run the test suite, but has no luck so far.

Any suggestions?

Thanks.

BTW, I am using Robotium package.

Quick solution:

adb -e uninstall your.test.package.name

Cleaner solution:

Back up a known good userdata-qemu.img emulator disk image and restore it before launching the emulator for new test run.

No, there's no way. But there's an easy way to uninstall it:

• Go to the menu, where you see the app
• Hit the menu button, click "Manage Apps"
• Click your app
• It will ask you if you really want to uninstall it
• Click "Yes" or "Uninstall" button. It will be uninstalled with all the data.

Hope this helps.

If your data is in a SQLite database you can change the database version to a higher version than the actual version.

private static final int DATABASE_VERSION = 2; //in the class that extends SQLiteOpenHelper

This will call the onUpgrade function, there you can delete the tables and create them again.

@Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
    //erase table
    db.execSQL("DROP TABLE IF EXISTS " + MY_TABLE); 
    //create again
    onCreate(db);
}

If you're not using SQLite just overwrite the files.

If the app data is the problem, you could just clear it rather than performing an uninstall. This link should help.
