App Getting Crashed in version 2.2

Question

I create an android App which works perfectly in Android 2.3+ all devices. But when i tried to run in 2.2 but it crashed and gives error in log as,

08-16 10:22:41.323: E/dalvikvm(442): Could not find class       'android.os.StrictMode$ThreadPolicy$Builder', referenced from method com.uks.android.mssga.activity.LoginActivity.onCreate

Code of LoginActivity is,

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.login);

    StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder()
            .permitAll().build();
    StrictMode.setThreadPolicy(policy);

            // Other stuff
 }

Please post your `onCreate` code for `LoginActivty`. As for the exception [StrictMode.ThreadPolicy.Builder](http://developer.android.com/reference/android/os/StrictMode.ThreadPolicy.Builder.html) is supported only since API level 9. — vKashyap, Aug 16 '12 at 05:16
@vKashyap I added code of on create method in edited question check it. — Anil Jadhav, Aug 16 '12 at 05:38
check [this answer](http://stackoverflow.com/questions/4610627/strictmode-for-lower-platform-versions) for using `StrictMode.ThreadPolicy.Builder` for lower versions. — vKashyap, Aug 16 '12 at 06:17

StrictMode.ThreadPolicy.Builder was introduced in Android 2.3 (API level 9), so attempts to call it in versions earlier than that will fail.

To stop it crashing on 2.2 and earlier you can choose to either:
* Remove the ThreadPolicy code (as it is a developer debug tool to provide warnings of bad things you are doing) or
* Use reflection to determine if the class exists before making use of it
