Android 我的应用程序没有'；t在从google play store下载时请求权限。我在清单文件中指定了位置权限

Mainifest文件

<?xml version="1.0" encoding="utf-8"?>

我的应用程序需要位置权限我以为google play store在下载时会询问，但用户必须手动设置位置。google play store应该以什么方式询问我应该在代码中添加什么？

如果您运行的是android API 23或更高版本，则需要在以下位置请求权限。要请求权限，您应该在使用使用权限的功能之前进行：

int MY_PERMISSIONS_REQUEST_LOCATION = 123;
if (ContextCompat.checkSelfPermission(thisActivity,
        Manifest.permission.ACCESS_FINE_LOCATION)
        != PackageManager.PERMISSION_GRANTED) {
    //app doesn't have permission yet

     ActivityCompat.requestPermissions(thisActivity,
                new String[]{Manifest.permission.ACCESS_FINE_LOCATION},
                MY_PERMISSIONS_REQUEST_LOCATION);
} else {
    // Permission has already been granted
}

public void onRequestPermissionsResult(int requestCode,
        String permissions[], int[] grantResults) {
    switch (requestCode) {
        case MY_PERMISSIONS_REQUEST_LOCATION: {

            if (grantResults.length > 0
                && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                // permission was granted
            } else {
                // permission denied
            }
            return;
        }

    }
}

然后覆盖onRequestPermissionsResult以查看用户是否已授予该权限：

int MY_PERMISSIONS_REQUEST_LOCATION = 123;
if (ContextCompat.checkSelfPermission(thisActivity,
        Manifest.permission.ACCESS_FINE_LOCATION)
        != PackageManager.PERMISSION_GRANTED) {
    //app doesn't have permission yet

     ActivityCompat.requestPermissions(thisActivity,
                new String[]{Manifest.permission.ACCESS_FINE_LOCATION},
                MY_PERMISSIONS_REQUEST_LOCATION);
} else {
    // Permission has already been granted
}

public void onRequestPermissionsResult(int requestCode,
        String permissions[], int[] grantResults) {
    switch (requestCode) {
        case MY_PERMISSIONS_REQUEST_LOCATION: {

            if (grantResults.length > 0
                && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                // permission was granted
            } else {
                // permission denied
            }
            return;
        }

    }
}

什么是-->我的权限请求位置对不起，这是一个简单的整型变量对不起，我不明白该如何使用这个变量？我已经在onCreate方法中粘贴了您提供的代码。第一个错误是-MY\u PERMISSIONS\u REQUEST\u location您需要在onCreate外部声明它，我已经编辑了答案，您可以看到：）您能告诉我如何使用运行时权限启用gps定位吗？
