I was trying to modify an default empty activity and form a default activity with action bar. There are two activities I made, which are both empty without actionbar. What I try to achieve is to click on the first activity(without actionbar) and navigate to the second activity(with actionbar). What I have done are:
1. add a menu
2. modify the second activity by changing the activity to AppCompatActivity
3. add a support library which is v7-appcompat (which was added as a referenced library. I am not sure whether it should be referenced lib or other format.)
The Manifest file part is shown below:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.tracker"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="14"
android:targetSdkVersion="21" />
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"

<activity
android:name=".MainActivity"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name=".SecondActivity"
android:label="#string/second" >
</activity>
</application>
</manifest>
The first activity is:
package com.example.tracker;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
public class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//get the button
Button button1 = (Button)findViewById(R.id.button1);
button1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent intent= new Intent(MainActivity.this,SecondActivity.class);
intent.setAction(Intent.ACTION_VIEW);
startActivity(intent);
}
});
}
}
The second activity is:
package com.example.tracker;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.support.v7.app.ActionBar;
import android.support.v7.app.AppCompatActivity;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.Toast;
public class SecondActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_second);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
return super.onOptionsItemSelected(item);
}
}
The menu in res is:
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
tools:context="com.example.tracker.MainActivity"
>
<item
android:id="#+id/myitem"
android:orderInCategory="2"
android:title="myitem"
app:showAsAction="never"/>
<item
android:id="#+id/action_settings"
android:orderInCategory="1"
android:title="action_settings"
app:showAsAction="never"/>
</menu>
The only observable problem is that the menu has an error which is written in the title of this problem. Currently, the first activity can run properly, however, when I click the button, the application stops.
By removing app:showAsAction="never" does not solve the problem.

I have created a simple app by adding action bar to it. And android studio didn't show any issue in the code, but my app keeps crashing when I run it.
I have two activities, in MainActivity I have one button and when you click it it supposed to take you to SecondActivity. And on SecondActivity there should be back arrow in action bar to get back to MainActivity.
Btw I'm using API 16. My activity extends Activity.

You are creating a recursion by calling return onCreateOptionsMenu(menu);
so it should be simply return true;
#Override
public boolean onCreateOptionsMenu(Menu menu){
getMenuInflater().inflate(R.menu.action, menu);
return true;
// return onCreateOptionsMenu(menu);
// call to itself , mean infinite recursion
}
The onCreateOptionMenu method recurses infinitely, so change it as below
#Override
public boolean onCreateOptionsMenu(Menu menu){
getMenuInflater().inflate(R.menu.action, menu);
return true;
}
Extend your activity with AppCompatActivity and use get getSupportActionBar() for backward compatibility
import android.support.v7.app.ActionBar;
import android.support.v7.app.AppCompatActivity;
public class SecondActivity extends AppCompatActivity {
and create actionbar using getSupportActionBar
ActionBar actionBar = getSupportActionBar();
actionBar.setDisplayHomeAsUpEnabled(true);
actionBar.setTitle("Second Activity");
Have big problem removing the Title Bar with Settings button.
When i try to remove it with code : android:theme="#android:style/Theme.NoTitleBar.Fullscreen"> or similary i get App crash.
Application consists of Splash screen, and Web View activity.

Try this
Change the Base application theme from Appcompat theme to Android theme and create a new theme for Splash screen.
<resources>
<!-- Base application theme. -->
<style name="AppTheme" parent="android:Theme.DeviceDefault.Light.DarkActionBar">
<!-- Customize your theme here. -->
</style>
<!-- Splash screen theme. -->
<style name="SplashTheme" parent="android:Theme.DeviceDefault.Light.NoActionBar">
<!-- Customize your theme here. -->
</style>
</resources>
Now make your MainActivity to extend Activity instead of ActionBarActivity
public class MainActivity extends Activity {
Open menu_main.xml and change
app:showAsAction="never"
to
android:showAsAction="never"
In AndroidManifest.xml set the theme for Splash Screen as follows
<activity
android:name=".splashscreen"
android:label="#string/app_name"
android:screenOrientation="portrait"
android:theme="#style/SplashTheme"
android:noHistory="true" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
Remove these lines from the SplashScreen.java
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
And you will get what you wanted. The error which you got is because you are switching from an Activity to ActionBarActivity
Even after defining com.facebook.LoginActivity in my AndroidManifest.xml file the logcat gives the same error and asks to define com.facebook.LoginActivity as activity. I have followed this https://developers.facebook.com/docs/android/login-with-facebook/v2.2#step2 tutorial.

The facebook login activity is com.facebook.LoginActivity with a capital 'L'. You're using a lower case l.

Do I have to download the google map key or something? Because i read on the internet that to load google maps on my application activity I have to download the key and only then will maps work! Is that why I am having this problem??
String url = "http://maps.google.com/maps?saddr=" + "9982878"+","+"76285774"+"&daddr="+"9992084"+","+"76286455";
Intent intent1 = new Intent(android.content.Intent.ACTION_VIEW, Uri.parse(url));
startActivity(intent1);
If you use the above your os will find the available app's to display the map. I tested the above in samsung galaxy s3. I had the option of choosing from default phone browser, chrome and Maps. All the apps were already installed on my phone.
It may be a browser or maps available in the phone. But this opens a new application from your activity.
If you want to display map in your application by customizing, then use google map api available for android.
http://www.youtube.com/watch?v=dSqLKIow7sY. You can follow the tutorial to get google map API Key. API key is required if your using Google maps API for displaying maps on your phone.
<uses-permission android:name="android.permission.INTERNET"/>//permission in manifest
After you get the key in your map.xml paste the key
<com.google.android.maps.MapView
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/mapview"
android:layout_width="fill_parent"
android:layout_height="350dp"
android:clickable="true"
android:apiKey="paste your key here" //paste key
/>
You can also use a webview. This is as good as opening the browser to display map.
public class MainActivity extends Activity {
WebView wv;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
wv= (WebView) findViewById(R.id.wv);
wv.getSettings().setPluginsEnabled(true);
WebSettings webSettings = wv.getSettings();
webSettings.setJavaScriptEnabled(true);
wv.loadUrl("http://maps.google.com/maps?saddr=" + "9982878"+","+"76285774"+"&daddr="+"9992084"+","+"76286455");
}
}
Xml Layout
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity" >
<WebView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/wv"></WebView>
</LinearLayout>
