Here is my Activity code

super.onCreate(savedInstanceState);
setContentView(R.layout.all_post);
CustomActionBar();
}

mActionBar.setDisplayShowHomeEnabled(false);
mActionBar.setDisplayShowTitleEnabled(false);
LayoutInflater mInflater = LayoutInflater.from(this);
View mCustomView = mInflater.inflate(R.layout.custom_action_bar, null);
TextView mTitleTextView = (TextView) mCustomView.findViewById(R.id.txtTitle);
mTitleTextView.setText("All Post");
ImageView imageButton = (ImageView) mCustomView
.findViewById(R.id.imgLeftMenu);
imageButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Toast.makeText(getApplicationContext(), "Refresh Clicked!",
Toast.LENGTH_LONG).show();
}
});
mActionBar.setCustomView(mCustomView);
mActionBar.setDisplayShowCustomEnabled(true);
}

</resources>

you are using Theme.AppCompat.Light.DarkActionBar so you should get your ActionBar by getSupportActionBar() method, not getActionBar()
if your extended Activity is from Android system then style is incorrect (AppCompat) and Activity gets some default styling without ActionBar, so getActionBar() return null
else if you want to use this AppCompat style it is applicable for AppCompatActivity (and then you use should getSupportActionBar())

need help on this
I tried to search on the errors that occured , but no luck .
then I got to know that I have to change the content.xml configuration .
The changes that I have done in content.xml are "device for preview" and "api version for preview" accordingly the device which is running in the emulator

Move from Activity class to AppCompatActivity class

I'm trying to develop an Android Application that will play through a video and then transition to another activity.
The issue I'm having is that the video needs to be played FullScreen and in order to do so I had to switch the extends from "AppCompatActivity" to "Activity" otherwise the program would crash when trying to run full screen.
So when I transition to the next activity I had to call that class with extends Activity as well.
Now when I try to implement a drawer sidebar I'm running into issues because the class doesn't extend AppCompat, and is having explicit issues with "getSupportActionBar"
(The video plays, and transitions to the second screen without issue it's just proceeding from there that I'm caught on)
Is there any way to have my second activity extend AppCompat, without it crashing? Or if anyone is aware of a more effective way of implementing this?
public class Main extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//this.requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.act_main);
VideoView splash = (VideoView) findViewById(R.id.SplashView);
Uri splashPath = Uri.parse("android.resource://" + getPackageName() + "/" + R.raw.phsplash);
splash.setVideoURI(splashPath);
splash.start();
final int interval = 7000;
Handler handler = new Handler();
Runnable runnable = new Runnable(){
public void run(){
Intent goHome = new Intent(Main.this, HomeView.class);
startActivity(goHome);
}
};
handler.postAtTime(runnable, System.currentTimeMillis()+interval);
handler.postDelayed(runnable, interval);
}
}
xml
<VideoView
android:id="#+id/SplashView"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_alignParentTop="true"
android:layout_alignParentBottom="true"
android:layout_alignParentLeft="true"
android:layout_alignParentRight="true" />
</RelativeLayout>
There is then the Home view (Not finished writing due to AppCompat issue)
public class HomeView extends Activity {
private ListView theDrawer;
private ArrayAdapter<String> theAdapter;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.home);
theDrawer = (ListView)findViewById(R.id.drawlayout);
theOptions();
setupDrawer();
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setHomeButtonEnabled(true);
}
private void theOptions(){
String[] panelarray = {"About PHam", "Upcoming Projects", "Idea Submit", "Locate PHam"};
theAdapter = new ArrayAdapter<>(this, android.R.layout.simple_list_item_1, panelarray);
theDrawer.setAdapter(theAdapter);
theDrawer.setOnItemClickListener(new AdapterView.OnItemClickListener(){
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id){
Toast.makeText(HomeView.this, "WTF is Toast!", Toast.LENGTH_SHORT).show();
}
});
}
private void setupDrawer(){
}
}
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:text="This is the Home Screen!"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/textView" />
<ListView
android:id="#+id/navlist"
android:layout_width="200dp"
android:layout_gravity="left|start"
android:layout_height="match_parent"
android:background="#ffeeeeee" />
</LinearLayout>
And then Finally the manifest
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.phsplash.captain.pcketham">
<application
android:allowBackup="true"
android:icon="#mipmap/phico"
android:label="#string/app_name"
android:supportsRtl="true"
android:theme="#android:style/Theme.NoTitleBar.Fullscreen">
<activity android:name=".Main">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name=".HomeView"
android:label="#string/app_name"
android:theme="#android:style/Theme.Black" >
</activity>
</application>
</manifest>

Extend your second class from AppCompatActivity instead of Activity.
public class HomeView extends AppCompatActivity
Happy coding. Cheers!
EDIT
For that greatness who just downvoted my answer, here is a snippet of the code without any error from Android Studio:
public class test extends AppCompatActivity{
private ListView theDrawer;
private ArrayAdapter<String> theAdapter;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.home);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setHomeButtonEnabled(true);
}
}
and here is the link to necessary documentation about support action bar.
To solve appCompat error, you need to add support library to your app build.gradle dependencies:
compile 'com.android.support:appcompat-v7:24.2.0'
Remember to always adjust your androidBuildToolsVersion, androidCompileSdkVersion, and androidTargetSdkVersion with the same API version. In this case, you need to use API Level 24.
Then you can extend your Activity with AppCompatActivity, something like:
public class HomeView extends AppCompatActivity {
...
}
Read more for Support Library from:
Support Library Features
Support Library Setup
UPDATE
Based on your error log, it means that you need to use AppCompat as the theme for you activity. Change styles.xml resource with AppCompat, something like this:
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">#color/colorPrimary</item> <!-- Your primary color -->
<item name="colorPrimaryDark">#color/colorPrimaryDark</item> <!-- Your dark color -->
<item name="colorAccent">#color/colorAccent</item> <!-- your accent color -->
</style>
Then add the theme to your Activity or Application in AndroidManifest.xml with android:theme="#style/AppTheme" something like this:
<application
android:allowBackup="true"
android:icon="#mipmap/phico"
android:label="#string/app_name"
android:supportsRtl="true"
android:theme="#style/AppTheme">

}

}
});
return view;
}
}
I tried following the guide in the documentation by facebook. Sorry for the code dump, I'm new to android and I have no idea what's causing my app to crash.
callbackManager = CallbackManager.Factory.create(); put this code below
FacebookSdk.sdkInitialize(getActivity().getApplicationContext());.
You have to initialze the callbackManager .
Cheers!!
you also need
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
callbackManager.onActivityResult(requestCode, resultCode, data);
}
for callbacks to work

MapFragment Crashes after app is killed on background

Implement googlemap on my project like this
from xml
<fragment
android:id="#+id/map"
android:layout_width="match_parent"
android:layout_height="250dp"
class="com.google.android.gms.maps.MapFragment"/>
from java
public class Search extends Fragment implementsOnMapReadyCallback {
View rootView;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
...
loadMap();
...
}
GoogleMap map;
MapFragment mapFragment;
public void loadMap() {
if (mapFragment == null) {
mapFragment = (MapFragment) getFragmentManager().findFragmentById(R.id.map);
mapFragment.getMapAsync(this);
}
}
#Override
public void onMapReady(GoogleMap googleMap) {
map = googleMap;
map.setMyLocationEnabled(true);
map.getUiSettings().setZoomControlsEnabled(true);
}
#Override
public void onDestroy() {
super.onDestroy();
getFragmentManager().beginTransaction().remove(mapFragment).commit();
}
This works fine even when i change from one fragment to another.
However, after some time, like when the app has been in the background for a long time, when i try opening the app again, it just crashes the app and i get this error

How can i fix this please.
I think this error can be ignored and app should load just fine.
Try this:
View rootView;
public View onCreateView(LayoutInflater inflater,
ViewGroup container, Bundle savedInstanceState)
{
// The last two arguments ensure LayoutParams are inflated
// properly.
if (rootView != null)
{
ViewGroup parent = (ViewGroup) rootView.getParent();
if (parent != null)
parent.removeView(rootView);
}
try
{
rootView = inflater.inflate( R.layout.yourMapFragment, container, false );
}
catch( InflateException ex )
{
}
...
return rootView;
}

Unable to find explicit activity class {}; have you declared this activity in your AndroidManifest.xml

I'm trying unzip some files in background, so I use IntentService like in google's tutorial. My service class declared in AndroidManifest like this:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="org.osmdroid">

android:minSdkVersion="16"
android:targetSdkVersion="21" />
<application

android:icon="#drawable/ecn_icon"
android:label="test" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />

</intent-filter>
</activity>
<activity
android:name=".SettingsActivity"
android:label="#string/title_activity_settings">
</activity>
<service
android:name=".UnZipService"
android:exported="false"/>
</application>
In activity, I have
IntentFilter intentFilter = new IntentFilter(DownloadManager
.ACTION_DOWNLOAD_COMPLETE);
receiverDownloadComplete = new BroadcastReceiver() {
#Override
public void onReceive(Context context, Intent intent) {
long reference = intent.getLongExtra(DownloadManager
.EXTRA_DOWNLOAD_ID, -1);
if (myDownloadReference == reference) {
...
switch (status) {
case DownloadManager.STATUS_SUCCESSFUL:
Intent mServiceIntent = new Intent(context, UnZipService.class);
mServiceIntent.setData(Uri.parse(savedFilePath));
startActivity(mServiceIntent);
break;
...
}
cursor.close();
}
}
};
registerReceiver(receiverDownloadComplete, intentFilter);
And service here:
public class UnZipService extends IntentService {
public UnZipService() {
super("UnZipService");
}
#Override
protected void onHandleIntent(Intent workIntent) {
String dataString = workIntent.getDataString();
Log.v("IntentURI", dataString);
Toast.makeText(this, "Installing....", Toast.LENGTH_SHORT).show();
}
It should show toast just for test, but I always get an error:

Both (class and activity) in same folder (org.osmdroid). Seems like paths is ok, but the problem appears and I have no more ideas...
You are starting a service as an activity
Change
Intent mServiceIntent = new Intent(context, UnZipService.class);
mServiceIntent.setData(Uri.parse(savedFilePath));
startActivity(mServiceIntent);
to
Intent mServiceIntent = new Intent(context, UnZipService.class);
mServiceIntent.setData(Uri.parse(savedFilePath));
startService(mServiceIntent); // Only this line is changed
Please declared this activity in your AndroidManifest.xml
