Android Coding (my app keeps crashing)

Question

hi ive started an app and wanted to test it so i use an avd and when the app starts it crashes and i was hoping somebody could help

this is my java class

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    MemoryInfo mi = new MemoryInfo();
    ActivityManager activityManager = (ActivityManager) getSystemService(ACTIVITY_SERVICE);
    activityManager.getMemoryInfo(mi);
    long availableMegs = mi.availMem / 1048576L;

    TextView manufacturerTextView = (TextView)findViewById(R.id.mem);
    manufacturerTextView.setText((int) mi.availMem);
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.activity_main, menu);
    return true;
}

}

LOGCAT

What exactly happens? Could you post the output of LogCat? You can find it in eclipse, or by using adb. — Kiril, Feb 06 '13 at 06:58

use

manufacturerTextView.setText(String.valueOf((int) mi.availMem));

instead

manufacturerTextView.setText((int) mi.availMem);

for showing Integer value in TextView

Only put up the part showing the crash. If you don't know how, then learn about how Android uses logcat first. http://stackoverflow.com/questions/8217500/how-to-print-stacktrace-for-an-exception-android – Simon Feb 06 '13 at 07:16
@user1934637 : you are getting error because of `manufacturerTextView.setText((int) mi.availMem);` line – ρяσѕρєя K Feb 06 '13 at 07:29
@user1934637 : use `manufacturerTextView.setText(String.valueOf(mi.availMem));` instead of `manufacturerTextView.setText((int) mi.availMem);` – ρяσѕρєя K Feb 06 '13 at 07:31

@ρяσѕρєя K it worked but how can i turn the avalible memory into MB format – user1934637 Feb 06 '13 at 07:41
@user1934637 : i think u will need to show `availableMegs` in TextView instead of `mi.availMem` – ρяσѕρєя K Feb 06 '13 at 07:44
