Android Keyevent injection requires system permissions

hi i am using key event injection using window manager but when i tested this application it gives me error 

  04-12 18:19:35.794: WARN/WindowManager(58): Permission denied: injecting key event        
  from pid 6290 uid 10039 to window Window{45034880  
   com.android.launcher/com.android.launcher2.Launcher paused=false} owned by uid 10020

   04-12 18:19:35.794: WARN/System.err(6290): java.lang.SecurityException: Injecting to 
    another application requires INJECT_EVENTS permission

 04-12 18:19:35.854: DEBUG/PhoneData(6290):

  04-12 18:19:36.048: WARN/System.err(6290):     at  
 android.os.Parcel.readException(Parcel.java:1247)

  04-12 18:19:36.048: WARN/System.err(6290):     at 
  android.os.Parcel.readException(Parcel.java:1235)

I also give the inject event permission is there any way to give a application system permissions.

Normally, you can't do this, for obvious security reasons. However, if this is for test purposes, you might find the Activity Testing documentation useful.

Hope this helps.

Only applications that are part of the firmware (i.e., signed by the firmware signing key) can hold the INJECT_EVENTS permission. If you are making your own device or firmware, this will be relevant. If you are creating an ordinary SDK application, you cannot inject events.
