我用地方选择器制作了一个应用程序。它在我的（API 19）模拟器和我的（android 6.0）朋友手机上打开，但在我的手机中它只是打开一个黑色活动，它关闭后（我的手机也是android 6.0），出现此错误：

代码：
PLACE_PICKER_REQUEST = 199;
PlacePicker.IntentBuilder builder = new PlacePicker.IntentBuilder();
Context context = this;
try {
startActivityForResult(builder.build(this), PLACE_PICKER_REQUEST);
} catch (GooglePlayServicesRepairableException e) {
e.printStackTrace();
} catch (GooglePlayServicesNotAvailableException e) {
e.printStackTrace();
}
结果代码：
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == PLACE_PICKER_REQUEST) {
if (resultCode == RESULT_OK) {
Place place = PlacePicker.getPlace(data, this);
Toast.makeText(this, place.getAddress(), Toast.LENGTH_LONG).show();
String toastMsg = String.format("Place: %s", place.getName());
// Toast.makeText(this, toastMsg, Toast.LENGTH_LONG).show();
TextView lbl_coordenadas = (TextView) findViewById(R.id.lbl_coordenadas);
coordenadas=""+place.getName();
lbl_coordenadas.setText("Coordenadas: "+coordenadas);
}
}
}
有没有人知道它可能是什么？提前谢谢。
