how to know that android:debuggable="true" from apk

android:debuggable="true"

Using the aapt tool you can check lots of things inside an apk. Use the following command:

aapt list -v -a myfile.apk

this shows hundreds of lines, but you must search the following text "android:debuggable"

this flag can have the values:

0x0: debuggable false
0xffffffff: debugabble true

in my case the entire line is the following

A: android:debuggable(0x0101000f)=(type 0x12)0xffffffff

Ups! My release build had the flag enabled ;)

For a good practise it should false. In application manifest under Application tag:

 android:debuggable="false"
