How to make a Release Android App debuggable

Let's say you want to access the application shared preferences in /data/data/com.mypackage.
You could try to run adb shell and then run-as com.mypackage ( or adb shell run-as com.mypackge ls /data/data/com.mypackage/shared_prefs), but on a production release app downloaded from an app store you're most likely to see:

run-as: Package 'com.mypackage' is not debuggable

While ADB's adb backup command will pull many of the files from the application's data directory, the files can be inconsistent with what is actually on the device. If you want to see what is actually on the device, you need to make the application debuggable.

For this task, we'll need apktool ( http://ibotpeaches.github.io/Apktool/ ). Once you have it setup, you'll need to find the path to the APK to pull it off the device. Run:

$ adb shell pm list packages -f -3

Find the package in the list (it should look something like /data/app/com.mypackage.apk=com.mypackage), and pull it off the device:

$ adb pull /data/app/com.mypackage.apk

Next, we need to disassemble the apk using apktool:

$ apktool d -o output-dir com.mypackage.apk

In output-dir, find AndroidManifest.xml and open it up in the text editor of your choice. In the application xml node, add the following xml attribute:

android:debuggable="true"

Now we need to reassemble the application. We do this by running:

$ apktool b -o com.mypackge.apk output-dir

Finally, we need to resign the APK so that the device will accept it:

$ keytool -genkey -v -keystore resign.keystore -alias alias_name -keyalg RSA -keysize 2048 -validity 10000
$ jarsigner -verbose -sigalg SHA1withRSA -digestalg SHA1 -keystore resign.keystore com.mypackage.apk alias_name

That's it! You should now be able to transfer the new com.mypackage.apk back to the device and run it. Now you should be able to run adb shell run-as ls /data/data/com.mypackage/ without getting the debuggable error.

I just used Apktool M and did that after opening it:

Applications → Installed Applications → Press on the app you want → Quick edit → Tick set apk as debugable → Press on SAVE → Install the saved APK normally.

Install the saved APK normally.

If I were to be using Firefox wouldn't that erase all of my data (as I want to export my firefox profile)? btw OP, adb pull gets me a no such file or directory and web results show no sign of anybody ever have successfully rooted a y9 2019, really out of luck here.. NVM lol it was the name. Props to @amahdy for https://gist.github.com/amahdy/87041554f62e384bee5766a958fd4f9a
