上面的代码不会抛出任何异常,也不会锁定motorola xoom平板电脑的屏幕.(Homeycomb和Icecream Sandwitch)相同的代码在其他Homeycomb和ICS平板电脑上完美运行.
我用Google搜索,但没有得到任何解决方案.有任何想法吗.....?
在Moto G6设备上运行Android应用程序时,我遇到两个问题(在其他设备或模拟器上没有此类问题)。在我的应用中,有一个简单的LoginActivity,成功登录后将启动MainActivity(在AsyncTask的onPostExecute中):
val intent = Intent(this@LoginActivity, MainActivity::class.java)
startActivity(intent)

从堆栈跟踪来看,它似乎主要发生在 Chrome 内核源代码中。希望有一种方法可以缓解相应的问题。
我有以下汇编代码片段,我试图理解.它是MC68332微控制器的组件.

我用google搜索BEQ,我发现它意味着在结果为零的分支,但我仍然不明白它的作用.它是否将最后一条指令的结果与0进行比较,如果为0,则返回到LOOP线?
我正在使用motorolla MC55扫描并在成功扫描时发出哔哔声,我需要禁用该功能,以便在扫描时根本不播放任何声音.
我有什么想法可以做到这一点?
我在开发工作时在LogCat中收到此错误.听起来像硬件故障.是吗?它有什么关系?我试过搜索,但发现只有人在谈论相机.这是在摩托罗拉Razr M.我的设备很古怪(反馈延迟经常在玩游戏时暂时解锁和冻结),我想知道这是否与它有关.谢谢!

在应用程序使用期间,我的BLE外围设备连接和断开多次.这样可以正常工作,但有时候app/phone不再重新连接到外围设备.
所有gatt命令都在主线程上运行,例如.
final BluetoothGatt gat = gatt;
Handler handler = new Handler(Looper.getMainLooper());
handler.post(new Runnable() {
@Override
public void run() {
// This code will be executed on the main thread
if (Looper.myLooper() == Looper.getMainLooper()) {
Log.e(TAG, "mGattCallback disconnect2: NOW ON MAIN THREAD :)");
}
gat.disconnect();
}
