startactivity crashed on execute

I have setup an activity to be executed from a menu button. The activity is started and briefly appears and then crashes. I have added added activity to manifest file. Code poseted below. I have recently switched form Eclipse to Android Studio and still learning the changes.

}
return super.onOptionsItemSelected(item);
}
}
I found the issue on the activity. I setup menu and back button to finish and exit the system so bluetooth will be killed. I removed these option and was able to execute the new activity.
#Override
protected void onDestroy() {
super.onDestroy();
// finish();
// System.exit(0);
}
#Override
protected void onStop() {
super.onStop();
// finish();
// System.exit(0);
}

try other way for startactivity, ex;
Intent intent = new Intent(MainActivity.this, Titles_Edit_Activity.class);
startActivity(intent);

I found the issue on the activity. I setup menu and back button to finish and exit the system so bluetooth will be killed. I removed these option and was able to execute the new activity.

Wear: Open my app with custom voice Start command, not working

Hi I'm following Google documentation to open a dummy App with the Start command but is not working for me.
I created a new default project using Android Studio wizard with a mobile and a wear module.
I didn't touch anything but 'android:label' of Wear Module manifest to "Hola" (hello in Spanish) and when I say "Iniciar Hola" ("Start Hello") Wear makes a google search with the "hola" keyword.
Wear module or mobile module aren't being launched.
What I'm missing :'( seems pretty easy from Google docs...
PS: I'm testing over BT on a wear device

Ok... the spanish word to Start an application is "Abrir" not "Iniciar", but on wear UI the menu entry to open apps is "Iniciar" so an applause for Google UX Team :'(

It looks like the voice commands are for launching apps on your phone, not launching a wear app.
I'm able to say "Start calculator" and it opens the calculator app on my phone.
What you could do is launch an activity on the phone and then that activity launches the wear app that you intended.

My app is crashing when I use the Theme.NoTitleBar in the menefest file

I've done this on my other apps and it worked fine. On my new app, when I run it I get a message box that says
"Unfortunately livebitcoinscharts has stopped",
The project is just from the template code generated by eclipse, I did not add anything to it
I'm using eclipse and tried putting a break point on the first line of code, which never went off.

<TextView

I think this is because you are usin ActionBarActivity which is under android suuport library v7 appcompat library which has to inflate a theme under Theme.AppCompat like Theme.AppCompat.Light.DarkActionBar
You can just inherit from Activity if you don't want actionbar.

Android Search Intent not Firing What am I doing wrong?

Ok I'm incredibly frustrated I've been trying to get a SearchView to work for hours now with no luck. I checked out how to handle this and I found a sample project and the sample project works great. I then implement the same exact things in my project and bam I'm screwed. The intent won't fire. I don't understand why. I followed this
I have all my activities in an activity folder but removed the Search and Main one to see if that was the case... it's not. In my Search Results activity I'm handling the intent. It looks like this currently.
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_search_result);
// get the action bar
ActionBar actionBar = getActionBar();
// Enabling Back navigation on Action Bar icon
actionBar.setDisplayHomeAsUpEnabled(true);
txtQuery = (TextView) findViewById(R.id.txtQuery);
handleIntent(getIntent());
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.search_result, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
#Override
protected void onNewIntent(Intent intent) {
setIntent(intent);
handleIntent(intent);
}
/**
* Handling intent data
*/
private void handleIntent(Intent intent) {
if (Intent.ACTION_SEARCH.equals(intent.getAction())) {
String query = intent.getStringExtra(SearchManager.QUERY);
txtQuery.setText("Search Query: " + query);
}
}
My Searchable XML looks like this.
<?xml version="1.0" encoding="utf-8"?>
<searchable xmlns:android="http://schemas.android.com/apk/res/android"
android:hint="#string/search_hint"
android:label="#string/app_name" />
For some reason the search hint is not appearing, Yet the string resource shows up and it's declared.
my options menu looks like this
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="#+id/search"
android:title="Search"
android:icon="#android:drawable/ic_search_category_default"
android:showAsAction="collapseActionView|ifRoom"
android:actionViewClass="android.widget.SearchView" />
<item android:id="#+id/Menu"
android:title="MENU"
android:showAsAction="collapseActionView|ifRoom"
/>
And my Manifest looks like this.
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/MyTheme" >
<activity
android:name=".MainActivity"
android:label="#string/app_name"
>
<meta-data
android:name="android.app.searchable"
android:resource="#xml/searchable" />
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name=".activities.MenuActivity"
android:label="#string/title_activity_menu"
android:theme="#style/IDME.Theme.Transparent" >
</activity>
<activity
android:name=".activities.CategoriesActivity"
android:label="#string/title_activity_categories" >
</activity>
<activity
android:name=".SearchResultActivity"
android:label="#string/title_activity_search_result"
>
<intent-filter>
<action android:name="android.intent.action.SEARCH" />
</intent-filter>
</activity>
</application>
</menu>
And my Search View inflator looks like this.
#Override
public boolean onCreateOptionsMenu(Menu menu)
{
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.options_menu, menu);
SearchManager searchManager =
(SearchManager) getSystemService(Context.SEARCH_SERVICE);
SearchView searchView =
(SearchView) menu.findItem(R.id.search).getActionView();
searchView.setSearchableInfo(
searchManager.getSearchableInfo(getComponentName()));
return true;
}
I cannot for the life of me figure out what's going on, I followed both guides to a tee, I cannot see what's wrong. I've messed around with metadata and I just really can't see the problem anymore. I'm stuck

I, too, followed the exact same (official Android) guide Setting Up the Search Interface and was in the same boat as the OP #rubsnick.
Turns out, all that that needs to be tweaked is--
Change
<activity
android:name=".MainActivity"
android:label="#string/app_name"
>
<meta-data
android:name="android.app.searchable"
android:resource="#xml/searchable" />
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
To
<activity
android:name=".MainActivity"
android:label="#string/app_name" >
<meta-data
android:name="android.app.default_searchable"
android:value=".SearchResultActivity" />
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
Notice the <meta-data code! (specifically, android:name)
Also, no need to specify the searchable xml resource here... instead, do that in the SearchResultActivity activity, as shown below...
Lastly, Modify <activity for SearchResultActivity, like so:
<activity
android:name=".SearchResultActivity"
android:label="#string/title_activity_search_result" >
<intent-filter>
<action android:name="android.intent.action.SEARCH" />
</intent-filter>
<meta-data android:name="android.app.searchable" android:resource="#xml/searchable" />
</activity>
The following SO thread does full justice as to why default_searchable and not searchable:
What's the difference between android.app.default_searchable and android.app.searchable meta-data?

your meta data is incorrect you must use:
<meta-data
android:name="android.app.searchable"
android:resource="#xml/searchable"
android:value="your package name of searchable activity.SearchResultActivity" />

Android Search Activity in Single Activity

I am trying to make my app consist a SINGLE activity. This activity should be able to create a search and also receive a search. Unfortunately, I am getting a "double" search bar in my SearchView when I click on the search button in the action bar. I mean that there is a search bar (dark-- SearchView) that appears for a second in the action bar, and then a second one (white) appears OVER the action bar. Any help? What am I doing wrong?
Sorry, this search thing is all new and confusing to me.

From Setting Up the Search Interface in the Android Documentation:
In your searchable activity, handle the ACTION_SEARCH intent by
checking for it in your onCreate() method.
Note: If your searchable activity launches in single top mode
(android:launchMode="singleTop"), also handle the ACTION_SEARCH intent
in the onNewIntent() method. In single top mode, only one instance of
your activity is created and subsequent calls to start your activity
do not create a new activity on the stack. This launch mode is useful
so users can perform searches from the same activity without creating
a new activity instance every time.

Please try to add the following attribute to your <activity> in your manifest file:
android:launchMode="singleTop"
This will make the same activity to receive the search intent.
More info here: http://developer.android.com/guide/topics/manifest/activity-element.html
Also, you have <intent-filter> declared twice, you should merge it into one element.

Okay, the problem had to do with calling onSearchRequested() in onOptionsItemSelected(MenuItem item). That is redundant when I have a SearchView and should only be called on older platforms.
So, I created a separate menu item for devices under Honeycomb. It is removed at runtime for newer devices. The SearchView is removed at runtime for older devices.
See updated code below:
#SuppressLint("NewApi")
#Override
public boolean onCreateOptionsMenu(Menu menu) {
mMenu = menu;
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
//remove old
menu.removeItem(R.id.search_old);
SearchManager searchManager =
(SearchManager) getSystemService(Context.SEARCH_SERVICE);
SearchView searchView =
(SearchView) menu.findItem(R.id.search).getActionView();
searchView.setSearchableInfo(
searchManager.getSearchableInfo(getComponentName()));
searchView.setIconifiedByDefault(false);
} else{
//remove new
menu.removeItem(R.id.search);
}
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.search_old:
onSearchRequested();
return true;
default:
return false;
}
}
#SuppressLint("NewApi")
#Override
public boolean onSearchRequested() {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.ICE_CREAM_SANDWICH) {
MenuItem mi = mMenu.findItem(R.id.search);
if(mi.isActionViewExpanded()){
mi.collapseActionView();
} else{
mi.expandActionView();
}
} else{
//onOptionsItemSelected(mMenu.findItem(R.id.search));
}
return super.onSearchRequested();
}
