I try to remove the support and bring it back. But nothing's happen. It always stops. This java code is for navigation table, and the page before it is for log in(online using mysql server and 000webhost).
Try adding this line in your activity tag in manifest:
android:theme="#style/AppTheme.NoActionBar">
like this:
<activity android:name=".UserProfile"
android:theme="#style/AppTheme.NoActionBar"/>
AppTheme.NoActionBar:
<style name="AppTheme.NoActionBar">
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
</style>

May Be A UI issue. As an example you have Designed your App for Mobile and tablet. If you have missed some codes in mobile Ui(XML file) it wont run in mobile. But it will work fine in Tablet. Please go through it.
android.content.res.Resources$NotFoundException: Resource ID #0x7f07007d
This is your problem.
open your R file to see which resource is creating the problem.
Another time the issue occurs is if you are trying to call set text while parsing an int which makes android look for a resource that maps to the integer value instead.
Posting code of the activity where the crash occurs might help

This is your problem, you're calling a method on a null variable:
GoogleApiClient client = null;
client.connect();
you need to initialize the client first. something like this
GoogleApiClient googleApiClient = new GoogleApiClient.Builder(this)
.enableAutoManage(this /* FragmentActivity */,
this /* OnConnectionFailedListener */)
.addApi(Drive.API)
.addScope(Drive.SCOPE_FILE)
.build();
Check this link.
In onStart(), you have:
GoogleApiClient client = null;
client.connect();
client is null. Hence, you cannot call connect() on it without getting a NullPointerException.

I am creating an app and added a new Resource Layout File. In Android Studio Preview, I am able to preview the file. The problem is that, While Calling that Layout, the app is getting crashed.
details_main_xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">
</LinearLayout>
DetailsMain.java
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
public class DetailsMain extends AppCompatActivity {
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.details_main);
}
}
I am calling this Activity fron Navigation bar Menu Item. The code is as follows.
public boolean onNavigationItemSelected(MenuItem item) {
// Handle navigation view item clicks here.
int id = item.getItemId();
if (id == R.id.nav_details) {
Intent in = new Intent(getApplicationContext(),DetailsMain.class);
startActivity(in);
} else if (id == R.id.nav_gallery) {
} else if (id == R.id.nav_slideshow) {
} else if (id == R.id.nav_manage) {
} else if (id == R.id.nav_share) {
} else if (id == R.id.nav_send) {
}
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
drawer.closeDrawer(GravityCompat.START);
return true;
}
What Mistake had I made?

You forget to Declare your Activity in manifest file.
<activity android:name="your.pakage.name.DetailsMain" />
you need to declare DetailsMain in your Manifest file
<application

android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name="com.example.DetailsMain"/>

You haven't declared activity in menifest file

Hello i'm making an application for Android and I added an ActionBarDrawerToggle to the app. When i select an item, the ActionBarDrawerToggle disappear.
What I want to do :
Create the ActionBarDrawerToggle in MainWindow.java [Done]
Create Profil.java and Planning.java and extend MainWindow into Profil and Planning to display the ActionBarDrawerToggle. [Problem]
I'm using :
UPDATE
Mainactivity :
public class MainWindow extends AppCompatActivity
implements NavigationView.OnNavigationItemSelectedListener {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setTheme(R.style.AppTheme_NoActionBar);
setContentView(R.layout.activity_mainwindow);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
fab.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG)
.setAction("Action", null).show();
}
});
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
drawer.setDrawerListener(toggle);
toggle.syncState();
NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);
}
#Override
public void onBackPressed() {
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
if (drawer.isDrawerOpen(GravityCompat.START)) {
drawer.closeDrawer(GravityCompat.START);
} else {
super.onBackPressed();
}
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.mainwindow, 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();
//noinspection SimplifiableIfStatement
if (id == R.id.nav_profil) {
return true;
}
return super.onOptionsItemSelected(item);
}
#SuppressWarnings("StatementWithEmptyBody")
#Override
public boolean onNavigationItemSelected(MenuItem item) {
// Handle navigation view item clicks here.
int id = item.getItemId();
if (id == R.id.nav_profil) {
Intent intent = new Intent(this, Profil.class);
startActivity(intent);
} else if (id == R.id.nav_planning) {
}
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
drawer.closeDrawer(GravityCompat.START);
return true;
}
}
the Profil :
public class Profil extends MainWindow {
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.content_profil);
System.out.println("Profil");
}
}
AndroidManifest.xml :
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.main">
<!-- To auto-complete the email text field in the login form with the user's emails -->
<uses-permission android:name="android.permission.GET_ACCOUNTS" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.READ_PROFILE" />
<uses-permission android:name="android.permission.READ_CONTACTS" />
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:supportsRtl="true"
android:theme="#style/AppTheme">
<activity
android:name=".Login"
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=".MainWindow"
android:label="#string/title_activity_mainwindow"></activity>
<activity
android:name=".Connection"></activity>
<activity
android:name=".Profil"></activity>
</application>
</manifest>
if you are using a material support lib you will have to add the action bar manually in the XML file
<android.support.design.widget.AppBarLayout
android:id="#+id/appbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:paddingTop="#dimen/appbar_padding_top"
android:theme="#style/AppBarOverlay">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:layout_scrollFlags="scroll|enterAlways"
app:popupTheme="#style/PopupOverlay"/>
</android.support.design.widget.AppBarLayout>
and in the java Activity file in onCreate() method add the following lines
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
Hope this works for you
Be sure #style/AppTheme theme not NoActionBar.
Android - Unable to find explicit activity class
and if you go to the map the app close
for the rest it work
