So I've been trying to pass an Extra (a single String) from one Activity to another via an Intent. In the following Activity, it is supposed to get the String from the last intent and use it as a condition for another change in Activity. I do not know if the Extras are not Put, not Gotten or not sent.
Here is the code which is supposed to send the Extras with the Intent:
public void btnDiffClicked(View view) {
int difficulty = view.getId();
if (difficulty == R.id.btnDiffEasy) {
Intent toeasy = new Intent(getApplicationContext(), EmotionCheckActivity.class);
Bundle b = new Bundle();
b.putString("diff", "EASY");
toeasy.putExtra("android.intent.extra.INTENT", b);
startActivity(toeasy);
} else if (difficulty == R.id.btnDiffMedium) {
Intent tomedium = new Intent(getApplicationContext(), EmotionCheckActivity.class);
Bundle b = new Bundle();
b.putString("diff", "MEDIUM");
tomedium.putExtra("android.intent.extra.INTENT", b);
startActivity(tomedium);
} else if (difficulty == R.id.btnDiffHard) {
Intent tohard = new Intent(getApplicationContext(), HardActivity.class);
startActivity(tohard);
}
}
And here is the code which is supposed to grab the Extras: @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_emotion_check);
final Intent startingIntent = getIntent();
Button btnHelpEmoCheck = (Button) findViewById(R.id.btnHelpEmoCheck);
btnHelpEmoCheck.setBackgroundColor(Color.TRANSPARENT);
Button btnCont = (Button) findViewById(R.id.btnCont);
btnCont.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View view) {
Bundle b = startingIntent.getBundleExtra("android.intent.extra.INTENT");
String diff = b.getString("diff");
if (diff == "MEDIUM") {
Intent tomedium = new Intent(getApplicationContext(), MediumActivity.class);
startActivity(tomedium);
} else if (diff == "EASY") {
Intent toeasy = new Intent(getApplicationContext(), EasyActivity.class);
startActivity(toeasy);
}
}
});
When I click the button which calls "btnContClicked" the activity crashes. I also tried getting the extras in onCreate(), when the variables are outside the onCreate()-method. It does not crash then but then the button does not do anything.

I suppose it is the very last line, yet I do not know what to do with it. All the other lines are referring to my TCP/IP connection. It throws errors when the server is not running, which is not the problem.
