The problem is that for new APIs, a file URI scheme is different than its scheme of old APIs. So creating a file using new File(apkPatch) will raise this exception for newer APIs.
So, you can pass the String to Uri.parse, not the File for solving this instead of using Uri.fromFile
So replace the below line of code:
intent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(new File(apkPatch)));
With:
intent.putExtra(Intent.EXTRA_STREAM, Uri.parse(apkPatch));
I have tried your solutions and it works pretty well but the apk file name is base.apk but i want my app name there(Chat Box) instead of base
Now to change the apk file name add below to the intent
intent.putExtra(Intent.EXTRA_SUBJECT, "Chat Box.apk");

So, can anyone helps me to figure out what is the problem ? BTW it only happens on some devices and i can't reproduce it while testing on my own devices.
and here is the method that causes the issue
public static void openCustomTab(Activity activity,
Uri uri) {
// create an intent builder
CustomTabsIntent.Builder intentBuilder = new CustomTabsIntent.Builder();
// Begin customizing
// set toolbar colors
intentBuilder.setToolbarColor(ContextCompat.getColor(activity, R.color.colorPrimary));
intentBuilder.setSecondaryToolbarColor(ContextCompat.getColor(activity, R.color.colorPrimaryDark));
// set start and exit animations
intentBuilder.setStartAnimations(activity, R.anim.slide_in_right, R.anim.slide_in_right);
intentBuilder.setExitAnimations(activity, android.R.anim.slide_in_left, android.R.anim.slide_out_right);
// build custom tabs intent
CustomTabsIntent customTabsIntent = intentBuilder.build();
// launch the url
customTabsIntent.launchUrl(activity, uri);
}
activity the launches the CustomTab in manifest
<activity
android:name=".ui.activities.productspecs.ProductSpecsActivity"
android:configChanges="orientation|screenSize"
android:label="#string/title_activity_product_specs"
android:theme="#style/AppTheme.Base"
android:windowSoftInputMode="adjustResize" />

That was the issue, https://github.com/alibaba/weex/issues/2139 it is related to Alibaba's app bug conflicts with a CustomTabs

Twitter No package identifier when getting value for resource number 0x00000000

I'm trying to implement twitter login in my android app.
I've followed the instructions ( https://dev.twitter.com/twitter-kit/android/twitter-login ) but when I call Fabric.with(this, new Twitter(authConfig)); the following exception occur.

I've tried to redo all the process using fabric plugin for android studio but it just redo the steps that I did manually and the problem persists.
Another exception occur when I tap on the login button:

MainActivity.java:
TwitterAuthConfig authConfig = new TwitterAuthConfig(TWITTER_KEY, TWITTER_SECRET);

LoginActivity.java:

});
#Override

super.onActivityResult(requestCode, resultCode, data);
loginButton.onActivityResult(requestCode, resultCode, data);
}
Any idea? I'm loosing too much time on this :(
Thank you!
Note: I don't have the twitter app installed. It's supposed to work in a webview.

Found the issue with the first exception. Apparently there are two different problems.
In my AndroidManifest.xml I was missing the attribute android:icon in <application ...>
I hope this will help others.

Activity crashes because of Intent with ACTION_SEND

I have an Intent to share a image from an view. It works, but once I canceled it to upload it on Instagram and I received an exception.
Google didn't help...
Intent

LinearLayout table=(LinearLayout) findViewById(R.id.table_linear);
table.setDrawingCacheEnabled(true);
Bitmap bitmap = table.getDrawingCache();
String imagepath=saveBitmap(bitmap);
//sv.setDrawingCacheEnabled(false);
Intent shareImage=new Intent();
shareImage.setAction(Intent.ACTION_SEND);

Broadcast receiver, check a checkbox preference state on bootup then send a notification

My problem is that when I try to read a checkbox preference state from a different activity on bootup then send a status bar notification. Then when the device boots the I get a force close error message popup then when I go into the error log I don't understand what happens.
The code for the broadcast receiver is shown below:
#Override
public void onReceive(Context context, Intent intent) {
if(intent.getAction().equals(Intent.ACTION_BOOT_COMPLETED)){
//this creates a reference to my preferences activity
Prefs prefsC = new Prefs();
SharedPreferences prefs = context.getSharedPreferences("Prefs", 0);
int status = Integer.parseInt(prefs.getString("bootup", "-1"));
if(status > 0){
//notifyNS is a method that sends the status bar notification
prefsC.notifyNS("", R.drawable.n);
//the setCheckedNS method is just a custom method I made to set the state of a checkbox preference
prefsC.setCheckedNS("icon", false);
}else{
prefsC.setCheckedNS("enable", false);
prefsC.setCheckedNS("icon", false);
prefsC.setCheckedNS("bootup", false);
}
}
}
So could you help me solve the issue on why it force closes on bootup. So basically what I want to do is read a checkbox preference state on bootup then send a status bar notification.
This is my error log response:

So I have no clue what to do from here.
Alright I have figured out what I have done wrong. What it is how I was connecting the context to the notificationManger construct method and Intent construct method.
Here is my new and revised code that works:
`public class BootupReceiver extends BroadcastReceiver {
private static final boolean BOOTUP_TRUE = true;
private static final String BOOTUP_KEY = "bootup";
#Override
public void onReceive(Context context, Intent intent) {
if(getBootup(context)) {
Toast toast2 = Toast.makeText(context, "getBootup", Toast.LENGTH_SHORT);
toast2.show();
NotificationManager NotifyM = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
Notification Notify = new Notification(R.drawable.n,
"NSettings Enabled", System.currentTimeMillis());
Notify.flags |= Notification.FLAG_NO_CLEAR;
Notify.flags |= Notification.FLAG_ONGOING_EVENT;
RemoteViews contentView = new RemoteViews(context.getPackageName(), R.layout.notification);
Notify.contentView = contentView;
Intent notificationIntent = new Intent(context, Toggles.class);
PendingIntent contentIntent = PendingIntent.getActivity(context, 0, notificationIntent, 0);
Notify.contentIntent = contentIntent;
Toast toast = Toast.makeText(context, "Notify about to be sent", Toast.LENGTH_SHORT);
toast.show();
int HELO_ID = 00000;
NotifyM.notify(HELLO_ID, Notify);
Toast toast1 = Toast.makeText(context, "Notify sent", Toast.LENGTH_SHORT);
toast1.show();
}
Intent serviceIntent = new Intent();
serviceIntent.setAction("com.brandon.labs.nsettings.NotifyService");
context.startService(serviceIntent);
}
public static boolean getBootup(Context context){
return PreferenceManager.getDefaultSharedPreferences(context).getBoolean(BOOTUP_KEY, BOOTUP_TRUE);
}
}
`
Since this question has gotten more than 100 views I thought it would be nice of me to post the code that works properly.
Note: I don't know why the closing curly bracket for the class isn't showing with the rest of the code it's a stackoverflow error

According to log ('java.lang.RuntimeException: Unable to instantiate receiver'), system is unable to create instance of your receiver class, because system is unable to find specified class (com.brandon.labs.nsettings.receivers.notifyBootup). I think it is probably problems with name (of receiver class) in your AndroidManifest.xml file, and it is not related to preferences.
In future, if you will get another exception, i recommend you to read carefully message of exception ;) and stack trace. Usually they contains the half of answer to your question.
And for popular mistakes - you can try to type exception text into Google (excluding some specific info such as name of class), and you will find solution very fast.

Have you added the following to your AndroidManifest.xml along with registering the BroadcastReceiver??
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
