在AndroidManifest.xml文件中，需要确保应用程序请求的所有权限都是合理的和必要的，包括敏感权限。同时，在访问敏感数据或功能之前，应该向用户请求授权。

下面是一个请求摄像头权限并使用摄像头的示例：

...

// Check for camera permission
if (ContextCompat.checkSelfPermission(thisActivity, Manifest.permission.CAMERA) == PackageManager.PERMISSION_GRANTED) {
    // Permission has already been granted, do camera related work
    // ...
} else {
    // Permission is not granted, request camera permission
    ActivityCompat.requestPermissions(thisActivity, new String[]{Manifest.permission.CAMERA}, PERMISSION_REQUEST_CAMERA);
}

...

// Handle permission request result
@Override
public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) {
    switch (requestCode) {
        case PERMISSION_REQUEST_CAMERA: {
            // If request is cancelled, the results array is empty
            if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                // Permission granted, do camera related work
                // ...
            } else {
                // Permission denied, handle accordingly
                // ...
            }
            return;
        }
        // Handle other permission requests if needed
        // ...
    }
}
