什么可以解决方案?
我正在开发一个蓝牙聊天应用程序.问题是,当我启用蓝牙时,应用程序启用蓝牙但会导致强制关闭.下次我启动相同的应用程序(启用蓝牙)它可以顺利运行!我已经搜索过,并且只获得了一些信息,说当我开始启用蓝牙的意图时,代码不会等待意图的结果
public void run() {
// 1. Check if Bluetooth is Enabled
if (!blue.isEnabled()) {
Intent enable_Bluetooth = new Intent(
BluetoothAdapter.ACTION_REQUEST_ENABLE);
startActivityForResult(enable_Bluetooth, 1);
}
// 2. Start Bluetooth Server
try {
Server = blue.listenUsingRfcommWithServiceRecord("dhiraj",
MY_UUID);
