在5.0上系统运行ok,把编译版本改成6.0后报下面这个错
Need ACCESS_COARSE_LOCATION or ACCESS_FINE_LOCATION permission...
阿西吧!!!这是问题是6.0系统全新的权限机制导致的[可以参考这篇文章] (http://jijiaxin89.com/2015/08/30/Android-s-Runtime-Permission/)
解决方案:
首先在AndroidManifest声明一下权限
<uses-permission-sdk-23 android:name="android.permission.ACCESS_COARSE_LOCATION"/>
然后在需要权限的地方请求权限
if (Build.VERSION.SDK_INT >= 23) {
//判断是否有权限
if (ContextCompat.checkSelfPermission(this,
Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
//请求权限
ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.ACCESS_COARSE_LOCATION},
MY_PERMISSIONS_REQUEST_ACCESS_COARSE_LOCATION);
//判断是否需要 向用户解释,为什么要申请该权限
if (ActivityCompat.shouldShowRequestPermissionRationale(this,
Manifest.permission.READ_CONTACTS)) {
Toast.makeText(this, "shouldShowRequestPermissionRationale", Toast.LENGTH_SHORT).show();
}
}else {
mBluetoothService.startLongScan();
}
}else {
mBluetoothService.startLongScan();
}
接收权限请求回调
@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[]
grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
switch (requestCode) {
case MY_PERMISSIONS_REQUEST_ACCESS_COARSE_LOCATION:
if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
// Permission Granted
mBluetoothService.startLongScan();
} else {
// Permission Denied
Toast.makeText(this, "ACCESS_COARSE_LOCATION Denied", Toast.LENGTH_SHORT)
.show();
}
break;
}
}
