Data sharing between two applications

by

Send data from Application 1 (for ex:Application 1 package name is “com.sharedpref1” ).

SharedPreferences prefs = getSharedPreferences("demopref",
                    Context.MODE_PRIVATE);
            SharedPreferences.Editor editor = prefs.edit();
            editor.putString("demostring", strShareValue);
            editor.commit();

Receive the data in Application 2( to get data from Shared Preferences in Application 1). 

    try {
            con = createPackageContext("com.sharedpref1", 0);//first app package name is "com.sharedpref1"
            SharedPreferences pref = con.getSharedPreferences(
                        "demopref", Context.MODE_PRIVATE);
            String your_data = pref.getString("demostring", "No Value");
        } 
    catch (NameNotFoundException e) {
                Log.e("Not data shared", e.toString());
         }

In both application manifest files add same shared user id & label,

 android:sharedUserId="any string" 
 android:sharedUserLabel="@string/any_string"

both are same… and shared user label must from string.xml

like this example.

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.xxxx"
android:versionCode="1"
android:versionName="1.0"
android:sharedUserId="any string" 
android:sharedUserLabel="@string/any_string">
