I am a beginner in android development and I have encountered some difficulty in running my app in the simulator. I am following chapter 12 of the head first textbook to design an app with tab navigation. It has four fragments and I am using the fragment pager adapter to navigate through the app. When I run the app in the simulator it is crashed with the error message "app has stopped working". My code for the main activity is as follows:
package com.hfad.bitsandpizzas;
import androidx.appcompat.app.AppCompatActivity;
import android.content.Intent;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import androidx.appcompat.widget.ShareActionProvider;
import androidx.appcompat.widget.Toolbar;
import androidx.core.view.MenuItemCompat;
import androidx.fragment.app.Fragment;
import androidx.fragment.app.FragmentManager;
import androidx.fragment.app.FragmentPagerAdapter;
import androidx.viewpager.widget.ViewPager;
public class MainActivity extends AppCompatActivity {
private ShareActionProvider shareActionProvider;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
SectionsPagerAdapter pagerAdapter =
new SectionsPagerAdapter(getSupportFragmentManager());
ViewPager pager = (ViewPager) findViewById(R.id.pager);
pager.setAdapter(pagerAdapter);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu_main, menu);
MenuItem menuItem = menu.findItem(R.id.action_share);
shareActionProvider =
(ShareActionProvider) MenuItemCompat.getActionProvider(menuItem);
setShareActionIntent("Want to join me for pizza?");
return super.onCreateOptionsMenu(menu);
}
private void setShareActionIntent(String text) {
Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("text/plain");
intent.putExtra(Intent.EXTRA_TEXT, text);
shareActionProvider.setShareIntent(intent);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.action_create_order:
Intent intent = new Intent(this, OrderActivity.class);
startActivity(intent);
return true;
default:
return super.onOptionsItemSelected(item);
}
}
private class SectionsPagerAdapter extends FragmentPagerAdapter {
public SectionsPagerAdapter(FragmentManager fm) {
super(fm);
}
#Override
public int getCount() {
return 4;
}
#Override
public Fragment getItem(int position) {
switch (position) {
case 0:
return new TopFragment();
case 1:
return new PizzaFragment();
case 2:
return new PastaFragment();
case 3:
return new StoresFragment();
}
return null;
}
}
}
the error message from the logcat is this

You are useing the Androidx support Library ,but in your xml layout ,you are useing the android.support.v4.view.ViewPager , you must change the ViewPager to Androidx support Library，use: androidx.viewpager.widget.ViewPager instead.
After Adding the Ad Mob in App , its working in higher version above 5.0 but its not working in 4.0 , i am getting the following exception

Please create a class
import android.content.Context;
import android.support.multidex.MultiDexApplication;
public class EnableMultiDex extends MultiDexApplication {
private static EnableMultiDex enableMultiDex;
public static Context context;
public EnableMultiDex(){
enableMultiDex=this;
}
public static EnableMultiDex getEnableMultiDexApp() {
return enableMultiDex;
}
#Override
public void onCreate() {
super.onCreate();
context = getApplicationContext();
}
}
and in your manifest give android:name="packagename.EnableMultiDex"
eg:
<application
android:name="YourPakageName.EnableMultiDex"
android:hardwareAccelerated="true"
android:icon="#drawable/wowio_launch_logo"
android:label="#string/app_name"
android:largeHeap="true"
tools:node="replace">
Let me know whether it solved your issue.
I have now completed all the scripting and designing with no compile time error but out of no where this run time error comes in and my app flashes away and do not get launched.
I have got all the files that it requires and everything done,
Please suggest now,
This is my MainActivity.java code thats probably throwing these exceptions
package com.example.dell.demologin;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;
import java.util.HashMap;
import activity.LoginActivity;
import helper.SQLiteHandler;
import helper.SessionManager;
public class MainActivity extends Activity {
private TextView txtName;
private TextView txtEmail;
private Button btnLogout;
private SQLiteHandler db;
private SessionManager session;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_register);
txtName = (TextView) findViewById(R.id.name);
txtEmail = (TextView) findViewById(R.id.email);
btnLogout = (Button) findViewById(R.id.btnLogout);
// SqLite database handler
db = new SQLiteHandler(getApplicationContext());
// session manager
session = new SessionManager(getApplicationContext());
if (!session.isLoggedIn()) {
logoutUser();
}
// Fetching user details from sqlite
HashMap<String, String> user = db.getUserDetails();
String name = user.get("name");
String email = user.get("email");
// Displaying the user details on the screen
txtName.setText(name);
txtEmail.setText(email);
// Logout button click event
btnLogout.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
logoutUser();
}
});
}
/**
* Logging out the user. Will set isLoggedIn flag to false in shared
* preferences Clears the user data from sqlite users table
* */
private void logoutUser() {
session.setLogin(false);
db.deleteUsers();
// Launching the login activity
Intent intent = new Intent(MainActivity.this, LoginActivity.class);
startActivity(intent);
finish();
}
}

ActionBar is used as Toolbar in material design. So add theme with no action bar and use
following to use Toolbar in xml.
<android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:iosched="http://schemas.android.com/apk/res-auto"
style="#style/HeaderBar"
iosched:theme="#style/ActionBarThemeOverlay"
iosched:popupTheme="#style/ActionBarPopupThemeOverlay"
android:id="#+id/toolbar_actionbar"
iosched:titleTextAppearance="#style/ActionBar.TitleText"
iosched:contentInsetStart="?actionBarInsetStart"
android:layout_width="match_parent"
android:layout_height="?actionBarSize" />
I found the solution of may error, i have to add the implements override methods of appCompatActivity. Below is the code by which i have fix it.
package com.drawer.sample;
import android.os.Bundle;
import android.support.v7.view.ActionMode;
import android.support.v7.widget.Toolbar;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.app.AppCompatCallback;
public class MainActivity extends AppCompatActivity implements AppCompatCallback {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar mToolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(mToolbar);
getSupportActionBar().setDisplayShowTitleEnabled(false);
}
#Override
public void onSupportActionModeFinished(ActionMode mode) {
// TODO Auto-generated method stub
super.onSupportActionModeFinished(mode);
}
#Override
public void onSupportActionModeStarted(ActionMode mode) {
// TODO Auto-generated method stub
super.onSupportActionModeStarted(mode);
}
}
And i can add the statusbar as well actionbar. :)
Have you ever try to add this code sample in your gradle file?
android {
configurations {
all*.exclude group: 'com.android.support', module: 'support-v4'
all*.exclude group: 'com.android.support', module: 'support-annotations'
} }
