Question

我有一个项目经过调试后在真机上发现，开始可以接受数据，在logcat中显示接收数据，但是手机最后会堆叠，logcat会显示以下错误：

08-22 15:33:41.782 1053-1121/? E/JavaBinder: !!! FAILED BINDER TRANSACTION !!!

我在互联网上搜索过，有人说是因为传输数据超过1Mb，或者有人使用Bitmap等等。但是我传递的数据不是那么大而且没有图片，而且起初数据可以传输，所以我不知道哪里出错了，附上我的密钥代码：

关于发送广播：

 Intent intent = new Intent("com.android.smartphone.SmartphoneSystemActivity");
intent.putExtra("4_ch_data", EEG_data);
sendBroadcast(intent);

关于接收器广播：

public class newStress extends Activity implements OnClickListener
{
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    requestWindowFeature(Window.FEATURE_INDETERMINATE_PROGRESS);
    setContentView(R.layout.newstress);
    Display display = this.getWindowManager().getDefaultDisplay();

    msgReceiver = new MsgReceiver();
    IntentFilter intentFilter = new IntentFilter();
    intentFilter.addAction("com.android.smartphone.SmartphoneSystemActivity");
    registerReceiver(msgReceiver, intentFilter);
}

public class MsgReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        int[] data = new int[4];
        double[] ddata = new double[4];
        int i;

        data = intent.getIntArrayExtra("4_ch_data");
        for (i = 0; i < 4; i++) {
            ddata[i] = (double) (data[i]);
            if (ddata[i] <= 8388607) {

                ddata[i] = ((ddata[i] + 8388608) * 2.4 / 8388607);
            } else {
                ddata[i] = ((ddata[i] - 8388608) * 2.4 / 8388607);
            }
            // Log.i("display", "data: "+ddata[i]);
        }
        Process(ddata);

    }
}

protected void onDestroy()
{
    super.onDestroy();

    Intent bluetoothserivce = new Intent (this,BluetoothActivity.class);
    stopService(bluetoothserivce);
    unregisterReceiver(msgReceiver);
    super.onDestroy();
}



}

提前致谢。

为什么logcat建议“FAILED BINDER TRANSACTION”
