Null Pointer Exception: Android

I am currently encountering a NullPointerException. I have used log statements to realize that it it shuts down when one specific line of code is read.

I have read lots about this type of exception, however I don't understand what is wrong with this specific statement.

try {

    Log.i(TAG, "1"); // Breaks here
    mDiaryId = ContentUris.parseId(launchingIntent.getData());
    Log.i(TAG, "2");

} catch (NumberFormatException e) {
    Log.i(TAG, "3");
    mDiaryId = -1;
}

You need to check for null after calling launchingIntent.getData(). Like this.

try {

    Log.i(TAG, "1");
    Uri data = getIntent().getData();
    if (data != null) { // <-- check data for null
        mDiaryId = ContentUris.parseId(data);
    } else {
        mDiaryId = -1;
        Log.i(TAG, "Data is null");
    }
    Log.i(TAG, "2");

} catch (NumberFormatException e){
    Log.i(TAG, "3");
    mDiaryId = -1;
}
