 # AndroidMiniDebugger
 A small tool to log your application inside your application with a floating UI component
+
+
+### Usage:
+
+Start the logging service:
+
+    Intent intent = new Intent(this, DebuggerService.class);
+    this.stopService(intent);
+    ContextCompat.startForegroundService(this, intent);
+    
+   ## note:
+   don't forget to grant "Draw over other apps" permission. (look into sample project "MainActivity.java")
+   
+   
+Finally use SRLog.java instead of android Log class:
+   
+    SRLog.d(TAG, "Message");
