Getting Nullpointer exception after updating to support Android design 22.2.1

My project worked perfectly before I upgraded to support Android design 22.2.1, after I updated and launched the program, I received the following error. The exception does not indicate which line in the code or the java file is causing the error, so I don’t know which code should be sent . It seems that the internal error is support for Android design.

My activity extends AppCompatActivity and my test device API 15 (Android 4.04).

I use NavigationView and DrawerLayout in my code.

My build.gradle

 android { compileSdkVersion 22 buildToolsVersion "22.0.1" defaultConfig { applicationId "com.stackoverflow.ranjith.androidprojdel" minSdkVersion 15 targetSdkVersion 22 versionCode 1 versionName "1.0" multiDexEnabled true } dependencies { compile fileTree(dir: 'libs', include: ['*.jar']) compile 'com.android.support:appcompat-v7:22.2.+' compile 'com.parse.bolts:bolts-android:1.+' compile 'com.android.support:cardview-v7:22.2.+' compile 'com.android.support:recyclerview-v7:22.2.+' compile 'com.google.android.gms:play-services-plus:7.5.0' compile 'com.google.android.gms:play-services-ads:7.5.0' compile 'com.android.support:design:22.2.+' compile 'joda-time:joda-time:2.8.1' }

An exception:

Update

When I roll back to 22.2.0, the error disappears, not sure what the problem is.

The problem is with the xml navigation navigation menu.

My looks like this:

 <?xml version="1.0" encoding="utf-8"?> <menu xmlns:android="http://schemas.android.com/apk/res/android"> <item android:id="@+id/navigation_subheader" android:title="Titulo"> <menu> <item android:id="@+id/navigation_sub_item_1" android:icon="@drawable/abc_btn_radio_material" android:title="sub-1"/> <item android:id="@+id/navigation_sub_item_2" android:icon="@drawable/abc_btn_rating_star_on_mtrl_alpha" android:title="sub-2"/> </menu> </item> </menu>

but if I switch to an icon with the ability to draw a project, it’s fixed:

 <?xml version="1.0" encoding="utf-8"?> <menu xmlns:android="http://schemas.android.com/apk/res/android"> <item android:id="@+id/navigation_subheader" android:title="Titulo"> <menu> <item android:id="@+id/navigation_sub_item_1" ----> android:icon="@drawable/some_local_drawable" android:title="sub-1"/> <item android:id="@+id/navigation_sub_item_2" ----> android:icon="@drawable/some_local_drawable" android:title="sub-2"/> </menu> </item> </menu>

Of course, this happens after upgrading to 22.2.1

I had the same problem and was able to avoid this with this code:

 View header = LayoutInflater.from(this).inflate(R.layout.nav_header_main, null); navigationView.addHeaderView(header); TextView text = (TextView) header.findViewById(R.id.textView); texto.setText("HELLO");
