Android 通过蓝牙将数据从Andread Wear Watch传输至手机
我目前正试图通过蓝牙将一个文本文件从可穿戴设备(MOTO 360 Android 5.1.1)发送到我的手机(MOTO X Android 4.4.4),但当我执行“onSendToPhone”方法时,我在手表上收到以下错误消息:Android 通过蓝牙将数据从Andread Wear Watch传输至手机,android,wear-os,android-bluetooth,moto-360,Android,Wear Os,Android Bluetooth,Moto 360,我目前正试图通过蓝牙将一个文本文件从可穿戴设备(MOTO 360 Android 5.1.1)发送到我的手机(MOTO X Android 4.4.4),但当我执行“onSendToPhone”方法时,我在手表上收到以下错误消息: No application can handle this action public void onSendToPhone(View view) { //... // inside method // Ch

File sendFile= new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS) + "<filename>");

intent.setType("text/plain");
intent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(sendFile));

}
也许有人能帮我找到解决办法;)
这是我用来从手表传输数据的代码:
No application can handle this action
public void onSendToPhone(View view)
{
//...
// inside method
// Check if bluetooth is supported
BluetoothAdapter btAdapter = BluetoothAdapter.getDefaultAdapter();
if (btAdapter == null) {
// Device does not support Bluetooth
// Inform user that we're done.
Log.d("TAG","Bluetooth not found");
return;
}
File sendFile= new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS) + "<filename>");
// bring up Android chooser
Intent intent = new Intent();
intent.setAction(Intent.ACTION_SEND);
intent.setType("text/plain");
intent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(sendFile));
startActivity(intent);
Log.d("TAG", "File is sent via Bluetooth");
}
public void onSendToPhone(视图)
{
//...
//内法
//检查是否支持蓝牙
BluetoothAdapter btAdapter=BluetoothAdapter.getDefaultAdapter();
if(btAdapter==null){
//设备不支持蓝牙
//通知用户我们已经完成了。
Log.d(“标签”,“未找到蓝牙”);
返回;
}
File sendFile=新文件(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_下载)+“”;
//打开Android选择器
意图=新意图();
intent.setAction(intent.ACTION\u SEND);
intent.setType(“文本/普通”);
intent.putExtra(intent.EXTRA_流,Uri.fromFile(sendFile));
星触觉(意向);
Log.d(“标签”,“文件通过蓝牙发送”);
}
不要为此使用蓝牙适配器。您必须使用Play服务来实现这一点
