Shared Preferences Not working over multiple contexts-CodePudding

Put into shared preferences code:

PreferenceManager.getDefaultSharedPreferences(Bookmarks.this).edit()
    .putString("togoto", link).apply();
String togoto = PreferenceManager.getDefaultSharedPreferences(Bookmarks.this)
    .getString("togoto", "no");
Toast.makeText(Bookmarks.this, "Will go to " togoto, Toast.LENGTH_SHORT).show();
setContentView(R.layout.activity_proxy_browser);

Intent myIntent = new Intent(Bookmarks.this, ProxyBrowserActivity.class);
startActivity(myIntent);

Get from shared prferences (In other context):

String togoto = PreferenceManager.getDefaultSharedPreferences(ProxyBrowserActivity.this).getString("togoto", "nogo");
Toast.makeText(ProxyBrowserActivity.this, "1 Going to " togoto, Toast.LENGTH_SHORT).show();
    
if (togoto != "no") {
    Toast.makeText(ProxyBrowserActivity.this, "Going to " togoto, Toast.LENGTH_SHORT).show();
    PreferenceManager.getDefaultSharedPreferences(ProxyBrowserActivity.this)
        .edit().putString("togoto", "no").apply();
} else {
    // no shared preferences
}

This does not appear to work and togoto returns no on the other context. How do I allow it to work over multiple contexts?

Please use

getSharedPreferences(KEY, MODE_PRIVATE) rather than 
PreferenceManager.getDefaultSharedPreferenceManager.

Your code is fine when you replace this.

If u create a default SharedPreference, it' name is context.getPackageName() "_preferences". And getDefaultSharedPreferences get that. When u set a name like "MyApp_preferences", getDefaultSharedPreferences will find nothing. Use getSharedPreferences.
