Same codes do not work in release mode (android share menu)

Question

Following codes work perfectly in debug mode:

menu_post_view.xml

<menu xmlns:android="http://schemas.android.com/apk/res/android"
      xmlns:tools="http://schemas.android.com/tools"
      xmlns:app="http://schemas.android.com/apk/res-auto"
      tools:context="com.mydream.bgz.activities.PostViewActivity">
    <item
            android:id="@+id/action_share"
            android:title="@string/action_share"
            app:actionProviderClass="android.support.v7.widget.ShareActionProvider"
            app:showAsAction="always"/>
</menu>

PostViewActivity.java

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.menu_post_view, menu);

    ShareActionProvider mShareActionProvider;
    MenuItem item = menu.findItem(R.id.action_share);
    mShareActionProvider = (ShareActionProvider) MenuItemCompat.getActionProvider(item);
    // mShareActionProvider.setOnShareTargetSelectedListener(this);
    Intent sharingIntent = new Intent(Intent.ACTION_SEND);
    sharingIntent.setType("text/plain");
    sharingIntent.putExtra(Intent.EXTRA_SUBJECT, str_mPostTitle);
    sharingIntent.putExtra(Intent.EXTRA_TEXT, str_mPostUrl);
    mShareActionProvider.setShareIntent(sharingIntent);

    return super.onCreateOptionsMenu(menu);
}

Everything happens in onCreate() method. I surrounded all of my codes with try-catch and got a following printed stack trace.

I have never faced with the problem like this. So, I could not understand why some normal codes do not work in release mode but debug build version. Please note that I did not write any share action menu related code in onCreate(). Please again, help me to understand why this problem occurred and how can I fix it?

That's because you are obfuscating your code on release mode.

Add this to your proguard config file.

-keep class android.support.v7.internal.** { *; }
-keep class android.support.v7.** { *; }
-keep interface android.support.v7.internal.** { *; }
-keep interface android.support.v7.** { *; }

Sure, obfuscation makes your app smaller, faster and "safer". With these lines you are preventing obfuscation of all the v7 library. Maybe you could be more precise and define the exact package that you don't want to be obfuscated. – ale.m Jun 13 '17 at 17:18

You can add this in proguard config.

-keep class android.support.** { *; }
-dontwarn android.support.**
-dontnote android.support.**

you can see in you log this line java.lang.NullPointerException: Attempt to invoke virtual method 'void android.support.v7.widget.bf.a(android.content.Intent)' on a null object reference

because the original code is obfuscated, so we should set in proguard that we should not obfuscate this files.

could you explain these lines please? – Mirjalal Jun 13 '17 at 17:07
thanks for explanation. +1 for it. but what are differences these lines with first answers' ? – Mirjalal Jun 13 '17 at 17:11

that will obfusticate only inside the files, android.support.v7 but in my case, I don't want to obfuscated any file inside android.support. Both are correct. – Muthukrishnan Rajendran Jun 13 '17 at 17:13

Same codes do not work in release mode (android share menu)
