My app have no errors in android studio, but in real test on android phone it jammed

I can't find my mistakes......
while studying social login(google, facebook), almost don't know what to do...
I tried my best, but couldn't find errors.
When I connect my android devices and run on them, my devices get jammed.
So I should force terminate my app.
here is my code

My problem is...
when I click play button on view from mainmenu.class. I can go to another page(go to view from userconfig.class). but when I click OK button in view from userconfig.class, I can't go to another page.

in USERCONFIG.CLASS change it to
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.user_config);
OK();
back();
}

call UserConfig.this.finish(); after startActivity()

singleTop searchable activity terminates when pressing back button

I have a ListActivity as the main activity of my app. Items in the list should be searchable but naturally I don't want to start the same activity over and over, hence singleTop. However, I do want the user to be able to return to the main list after a search and that's causing me some trouble. Currently, pressing back after a search will terminate the app. One solution is to make a copy of the list activity specifically to handle searching but I can't imagine that's the best way to go about it. I have briefly tried activity-alias but every permutation I have tried either doesn't change the behaviour or performs a Web search instead. I don't know if activity-alias is even appropriate but I've included an example anyway.
My question is, is there a best way to achieve what I'm trying to do that doesn't involve superfluous code maintenance?
<activity
android:name=".MainListActivity"
android:label="#string/app_name"
android:launchMode="singleTop">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity-alias
android:name=".SearchList"
android:targetActivity=".MainListActivity"
android:launchMode="singleTop">
<intent-filter>
<action android:name="android.intent.action.SEARCH" />
</intent-filter>
<meta-data
android:name="android.app.searchable"
android:resource="#xml/searchable" />
</activity-alias>

I found an embarrassingly simple solution.
Manifest:
<activity
android:name=".MainListActivity"
android:label="#string/app_name"
android:launchMode="singleTop" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
<intent-filter>
<action android:name="android.intent.action.SEARCH" />
</intent-filter>
<meta-data
android:name="android.app.searchable"
android:resource="#xml/searchable" />
</activity>
List/search activity:
public class MainListActivity extends FragmentActivity
implements LoaderManager.LoaderCallbacks<Cursor>
{
private boolean searching = false;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.list_cheapest);
dbHelper = new DatabaseHelper(this);
String[] fromColumns = {"pname", "store", "unit_price"};
int[] toViews =
{R.id.entryProductName, R.id.entryStore, R.id.entryUnitPrice};
adapter = new SimpleCursorAdapter(this, R.layout.cheapest_row_entry,
null, fromColumns, toViews);
ListView lv = (ListView)findViewById(android.R.id.list);
lv.setAdapter(adapter);
lv.setEmptyView(findViewById(android.R.id.empty));
lv.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> l, View v, int position,
long id) {
searching = false;
startActivity(new Intent(getBaseContext(),
EditProductActivity.class).putExtra("pid", ""+id));
}
});
handleIntent(getIntent());
}
#Override
public void onBackPressed() {
if (searching) {
searching = false;
getSupportLoaderManager().restartLoader(LOADER_MAIN, null, this);
} else {
finish();
}
}
#Override
protected void onNewIntent(Intent intent) {
handleIntent(intent);
}
private void handleIntent(Intent intent) {
if (Intent.ACTION_SEARCH.equals(intent.getAction())) {
searching = true;
filter = intent.getStringExtra(SearchManager.QUERY);
getSupportLoaderManager().restartLoader(LOADER_SEARCH, null, this);
} else {
getSupportLoaderManager().initLoader(LOADER_MAIN, null, this);
}
}
...
}
However, I did first get activity-alias working. I'm including it for posterity.
Manifest:
<activity
android:name=".MainListActivity"
android:label="#string/app_name"
android:launchMode="singleTop" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />

android:value=".SearchListActivity" />
</activity>
<activity-alias
android:name=".SearchListActivity"
android:launchMode="singleTop"
android:targetActivity=".MainListActivity" >
<intent-filter>
<action android:name="android.intent.action.SEARCH" />
</intent-filter>
<meta-data
android:name="android.app.searchable"
android:resource="#xml/searchable"
android:value=".SearchListActivity" />
</activity-alias>
List/search activity:
public class MainListActivity extends FragmentActivity
implements LoaderManager.LoaderCallbacks<Cursor>
{
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.list_view);
...
lv.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> l, View v, int position,
long id) {
if (Intent.ACTION_SEARCH.equals(getIntent().getAction())) {
finish();
}
startActivity(new Intent(getBaseContext(),
EditProductActivity.class).putExtra("pid", ""+id));
}
});
handleIntent(getIntent());
}
#Override
protected void onNewIntent(Intent intent) {
handleIntent(intent);
}
private void handleIntent(Intent intent) {
if (Intent.ACTION_SEARCH.equals(intent.getAction())) {
filter = intent.getStringExtra(SearchManager.QUERY);
getSupportLoaderManager().restartLoader(LOADER_SEARCH, null, this);
} else {
getSupportLoaderManager().initLoader(LOADER_MAIN, null, this);
}
}
...

unable to send Broadcast from activity to other: android

i have problem with sending Broadcast receive from one activity to other ..its not working my code is below..pls refer to it ..
sending class is:
public class SendBroadcast extends Activity {
public static String BROADCAST_ACTION = "com.unitedcoders.android.broadcasttest.SHOWTOAST";
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button button1 = (Button) findViewById(R.id.button1);
button1.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
sendBroadcast();
}
});
}
public void sendBroadcast(){
Intent broadcast = new Intent();
broadcast.setAction("com.unitedcoders.android.broadcasttest.SHOWTOAST");
sendBroadcast(broadcast);
}
}
and reciving class is :
public class ToastDisplay extends Activity {
private BroadcastReceiver receiver = new BroadcastReceiver() {
#Override
public void onReceive(Context context, Intent intent) {
Log.i("asdasd","sdasdasd");
// TODO Auto-generated method stub
Toast.makeText(getApplicationContext(), "%%%%%%%%%%%%received", Toast.LENGTH_SHORT).show();
}
};
#Override
protected void onResume() {
IntentFilter filter = new IntentFilter();
filter.addAction(SendBroadcast.BROADCAST_ACTION);
registerReceiver(receiver, filter);
super.onResume();
}
#Override
protected void onPause() {
unregisterReceiver(receiver);
super.onPause();
}
}
