Of course, Android Studio is a development tool, so it’s not exactly a plug-and-play installation for your preferred development platform. For Java or Kotlin Android apps, there’s no better option in terms of ease of development. It’s Google’s official IDE (integrated development environment) made specifically for developing native Android apps. Public class MainActivity extends AppCompatActivity implements View.If you’re just getting started in Android app development, you may or may not know of Android Studio. The code for the MainActivity.java is given below. The code for the activity_second.xml layout is given below. The first button would pass a bundle with data into the SecondActivity.java while the second button would pass an empty bundle Hence it’s recommended to add null checks for the Bundle as well as the retrieved values. If the key doesn’t map to any value, it may lead to NullPointerException. String title = bundle.getString("key_1") Intent intent = new Intent(this,SecondActivity.class) īundle.putString("key_1", "MainActivity greeted you with a HI") ĭata from a Bundle is retrieved in the SecondActivity.java in the following manner. putCharSequenceArrayList(String key, ArrayList value), getCharSequenceArrayList(String key, ArrayList value value).putCharSequenceArray(String key, CharSequence value), getCharSequenceArray(String key, CharSequence value).putCharSequence(String key, CharSequence value), getCharSequence(String key, CharSequence value).putCharArray(String key, char value), getBooleanArray(String key, char value).putChar(String key, char value), getChar(String key, char value).putBooleanArray(String key, boolean value), getBooleanArray(String key, boolean value).putBoolean(String key, boolean value), getBoolean(String key, boolean value).putLongArray(String key, long value), getLongArray(String key, long value).putLong(String key, long value), getLong(String key, long value).

putStringArrayList(String key, ArrayList value), getStringArrayList(String key, ArrayList value value).putStringArray(String key, String value), getStringArray(String key, String value).putString(String key, String value), getString(String key, String value).putIntegerArrayList(String key, ArrayList value), getIntegerArrayList(String key, ArrayList value value).putIntArray(String key, int value), getStringArray(String key, int value).putInt(String key, int value), getInt(String key, int value).Following are the major types that are passed/retrieved to/from a Bundle.
