java.lang.SecurityException：权限拒绝：需要 com.huawei.android.launcher.permission.WRITE_SETTINGS

Question

当应用程序在手机 HUAWEI ALE-21 Android 6.0 API 23 上运行时，我正在努力解决这个问题。我的应用程序崩溃了，我收回了这些错误。

您需要检查权限并请求权限，如下所示：

代码示例：

// Here, thisActivity is the current activity
if (ContextCompat.checkSelfPermission(thisActivity,
        "com.huawei.android.launcher.permission.WRITE_SETTINGS")
        != PackageManager.PERMISSION_GRANTED) {

    // Permission is not granted
    // Should we show an explanation?
    if (ActivityCompat.shouldShowRequestPermissionRationale(thisActivity,
            "com.huawei.android.launcher.permission.WRITE_SETTINGS")) {
        // Show an explanation to the user *asynchronously* -- don't block
        // this thread waiting for the user's response! After the user
        // sees the explanation, try again to request the permission.
    } else {
        // No explanation needed; request the permission
        ActivityCompat.requestPermissions(thisActivity,
                new String[]{"com.huawei.android.launcher.permission.WRITE_SETTINGS"},
                MY_PERMISSIONS_REQUEST_WRITE_SETTINGS);

        // MY_PERMISSIONS_REQUEST_WRITE_SETTINGS is an
        // app-defined int constant. The callback method gets the
        // result of the request.
    }
} else {
    // Permission has already been granted
}
