I've been debugging for hours now and still no luck. I made a RSS Reader using Android fragments. It works amazingly well on devices running Android 4.0.x to 4.1.x but crashes on start on Android 4.2.x devices.
I'd really appreciate any help I can get.

Okay, so I figured out what was wrong.
I was focusing on the wrong error. The error was actually in my method GetAllThePosts() which is called when the app is started, because of which the layout could not be inflated. And it's not even an error because it works perfectly well in all other Android versions.
For some reason, you can't change the view of menu items while the app is starting in Android 4.2.x
The code responsible was:
private class GetAllThePosts extends AsyncTask<Void, Void, Void> {
protected void onPreExecute() {
RefreshMenuButton.setActionView(R.layout.action_progress);
RefreshMenuButton.expandActionView();
...
I just added a conditional statement to check if we were on Android 4.2 and higher. If we are it won't run the first time.

I'm working on an Android App and I want to use 4 tabs for navigation using Activites for each tab. here I added the code which I have tried
this is my TabHostActivity
public class TabHostActivity extends Activity {
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.tab_host);
context = getApplicationContext();
TabHost tabHost = (TabHost) findViewById(android.R.id.tabhost);
LocalActivityManager mLocalActivityManager = new LocalActivityManager(this, false);
tabHost.setup(mLocalActivityManager);
TabHost.TabSpec tag4= tabHost.newTabSpec(TAB_4_TAG);
TabHost.TabSpec tag3= tabHost.newTabSpec(TAB_3_TAG);
TabHost.TabSpec tag2= tabHost.newTabSpec(TAB_2_TAG);
TabHost.TabSpec tag1= tabHost.newTabSpec(TAB_1_TAG);
tag1.setIndicator("AboutCollege", getResources().getDrawable(R.drawable.college)).setContent(new Intent(this, AboutCollegeActivity.class));
tag2.setIndicator("Focus of Course", getResources().getDrawable(R.drawable.course)).setContent(new Intent(this, AboutCollegeActivity.class));
tag3.setIndicator("Admision", getResources().getDrawable(R.drawable.admission)).setContent(new Intent(this, AboutCollegeActivity.class));
tag4.setIndicator("Contact Details", getResources().getDrawable(R.drawable.contact)).setContent(new Intent(this, AboutCollegeActivity.class));
tabHost.addTab(tag1);
tabHost.addTab(tag2);
tabHost.addTab(tag3);
tabHost.addTab(tag4);
}
}
this is my tabHost.xml
<?xml version="1.0" encoding="utf-8"?>
<TabHost xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#android:id/tabhost"
android:layout_width="match_parent" android:layout_height="match_parent">

android:layout_height="wrap_content" />
<FrameLayout
android:id="#android:id/tabcontent"
android:layout_width="fill_parent"
android:layout_height="fill_parent"/>
</LinearLayout>
</TabHost>
this is the error log

When I click the button from another activity it moves to this tab host. here I got the exception like in the error log. I have searched but unfortunately, I didn't get a clear answer.
hope this helps to U

This class was deprecated in API level 13.
New applications should use Fragments instead of this class; to continue to run on older devices, you can use the v4 support library which provides a version of the Fragment API that is compatible down to DONUT.

I use the Google Plus SDK in my Android app. On some rare devices, I have got the following crash when my view containing Google Plus buttons is inflated:
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main); // CRASH HERE
....
}
My GooglePlus buttons are in xml like this:
<com.google.android.gms.common.SignInButton
android:id="#+id/sign_in_button"
....
/>
<com.google.android.gms.plus.PlusOneButton
xmlns:plus="http://schemas.android.com/apk/lib/com.google.android.gms.plus"
android:id="#+id/plus_one_button"
...
/>
Below the log. Any idea on the way to solve this issue ?
Thanks !!

Examples of devices where I have got the issue (it happens only on few devices of each type otherwise I would have much more crash reports):
crane-a702jhorange
MW0712
Tablet S (nbx03)
List item
Galaxy Y (GT-S5360B)
Galaxy Y Duos (GT-S6102)
rk2928sdk
rk2928sdk
rk2928sdk
Galaxy Note II(t03g)
Galaxy Mini (GT-S5570I)
e1901_v77_jdt1_9p017_fwvga
Nexus S (crespo)
Galaxy Ace (GT-S5830i)
crane-inet
ITP-R208W (rk30sdk)
I received an ACRA report from an rk2928sdk with the same exception. Fortunately I was storing the information from GooglePlayServicesUtil.isGooglePlayServicesAvailable(this) in the report. This call returned SERVICE_INVALID.
I am using the PlusOneButton in a very basic "About" activity so I decided to duplicate this activity and remove the PlusOneButton from the layout second. Now I´m catching the InflateException and use the layout without the button if the exception gets catched.
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View rootView;
try {
rootView = inflater.inflate(R.layout.activity_about, container, false);
} catch (InflateException e) {
rootView = inflater.inflate(R.layout.activity_about_fallback, container, false);
}
return rootView;
}
The try-catch could be replaced by a check if .isGooglePlayServicesAvailable() returns a sane value. But I don't know which of those return values guarantee the availability of the PlusOneButton so I will leave it with the ugly try-catch.
Just add plus play service to you app:
compile 'com.google.android.gms:play-services-plus:10.0.1'
I've seen dozens of similar problems but none have seemed to fix my issue. I have an app that uses google maps v2 (previously used v1). I imported google-play-services and android-support-v4, and created an activity that extended SupportFragment (also tried just fragment). I added all permissions and my key to the manifest, and created a fragment in my layout folder which defines the map. However, my app crashes every time I call setContentView on my fragment within my activity. I imported android.support.v4.app.FragmentActivity and android.support.v4.app.Fragment in this activity, but get an error trying to inflate the fragment. The logcat log is listed below. Thanks in advance!

I just put together a new Android project in Eclipse, and so far I only have one package with one activity (the auto-generated code from Eclipse), and all I did was add two buttons to the main.xml layout file.
When I try to debug the app, the emulator crashes and I get the error "Binary XML file line #31: Error inflating class android.widget.FrameLayout."
I'm not even using FrameLayout!
Here is the layout file:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:background="#99CCFF">
<Button
android:id="#+id/btn1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="New" />
<Button
android:id="#+id/btn2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Save" />
</LinearLayout>
And here is the main Activity file (again, this is just the default code that Eclipse generates when you create a new project):
package com.myapp.main;
import android.app.Activity;
import android.os.Bundle;
public class MyApp extends Activity {
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}
}
And just for the heck of it, here's the manifest file as well:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.myapp.main"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk android:minSdkVersion="8" />
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name" >
<activity
android:name="com.myapp.main.MyApp"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
So far as I can see, this is 99% auto-generated code, and I can see no reason why I would be getting an InflateException on "FrameLayout" when I'm not even using a FrameLayout.
So very confused ...
Here is what I get in LogCat:

I'm having trouble seeing what's wrong with your code as well. Could you copy and paste the entire stack trace you get when your app crashes? I think it might give us more of an insight as to what is going on.
You can either get the stack trace from Logcat in Eclipse, or you can open a terminal and type "adb logcat"
i'm trying to initialize my textview using a static string whenever i launch this activity but emulator always force closes the activity.. can anyone help me out?
Here's the code:

/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
// to set the contacts value in status module
TextView v1 = (TextView) findViewById(R.id.stat_con1);
v1.setText(phoneno[0]);

Have you tried to clean your project? This looks just like such kind of error (because everything else seems perfectly fine). If you develop in Eclipse go to project -> clean. Select all projects. Afterwords you might need to also rebuild. Also if this does nto help, try restarting your IDE.
From the code you posted, I can see two possible errors:
TextView v1 is null, which means the layout file doesn't have any TextView with the id R.id.stat_con1
the view with the id R.id.stat_con1 is not a TextView and you fail when casting to a TextView
Update:
Caused by: java.lang.NullPointerException
at com.example.service.ServiceAct.onCreate(ServiceAct.java:31)
Check line 31... something in that line is null.
