Introspy: trace file (introspy.db) is not created I am trying to use Introspy tool in Android device, but the trace file (introspy.db) is not being created. Kindly any help if you have tried using this.
I know this was asked a long time ago but in case anyone else who searches needs an answer:

I also had this problem when running Introspy on a Galaxy S4 running KitKat (4.4.2).  I have ran Introspy with zero problems on a Nexus S running JellyBean (4.2.1).  Because of this I believe it is an Android SDK problem with newer versions.  

If you look at the AndroidManifest file for Introspy-Android Core, the targetSdkVersion is 18, which denotes Jellybean.  I looked at logcat files and found that I was getting the error:

Permission Denial: get/set setting for user asks to run as user -2 but is calling from user 0; this requires android.permission.INTERACT_ACROSS_USERS_FULL


I simply added this permission to the Android Core AndroidManifest.xml file as well as the Android Config AndroidManifest.xml with the command:

&lt;uses-permission android:name="android.permission.INTERACT_ACROSS_USERS_FULL"/&gt;


I then just recompiled both binaries and it worked!  Hope this helps.
