    setContentView(R.layout.activity_main);

    tvPlaceAPI = (TextView) findViewById(R.id.tv_place_id);

    btPlacesAPI = (Button)findViewById(R.id.bt_ppicker);
    btPlacesAPI.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {

            PlacePicker.IntentBuilder builder = new PlacePicker.IntentBuilder();
            try {

                startActivityForResult(builder.build(MainActivity.this), PLACE_PICKER_REQUEST);


            } catch (GooglePlayServicesRepairableException e) {
                e.printStackTrace();
            } catch (GooglePlayServicesNotAvailableException e) {
                e.printStackTrace();
            }
        }
    });

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {

    if (requestCode == PLACE_PICKER_REQUEST) {
        if (resultCode == RESULT_OK) {
            Place place = PlacePicker.getPlace(this,data);
            String toastMsg = String.format(
                    "Place: %s \n" +
                            "Alamat: %s \n" +

<meta-data
        android:name="com.google.android.maps.v2.API_KEY"
        android:value="Server_key" />

Key should be server key instead of android api key refer this link http://www.androidrey.com/google-places-api-for-android-place-picker/
