すでにGCMに登録されているデバイスがあります。検索してみましたが、似たような問題は見つかりませんでした。ほとんどのユーザーは、getRegistrationIdが空でない文字列を返すのに問題があるようです。これがエラーを引き起こす理由についてのアイデアはありますか?
public class UploadOption extends Activity{
Intent extras = getIntent();
String optionid = extras.getStringExtra("KEY_OPTION");
String duration = extras.getStringExtra("KEY_DURATION");
String reward = extras.getStringExtra("KEY_REWARD");
@Override
public void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.debug_layout);
final String regId = GCMRegistrar.getRegistrationId(this);
TextView tvDebug = (TextView) findViewById(R.id.tvDebug);
tvDebug.setText(regId);
// Stores option id, php grabs option.
//new Upload().execute();
}
}
エラーログは以下のとおりです。
