应用程序不要求获得权限

Question

我有此代码可获得以下权限(READ_PHONE_STATE, READ_CONTACTS, WRITE_CONTACTS):

int permissionCheck = ContextCompat.checkSelfPermission(this, android.Manifest.permission.READ_PHONE_STATE);
int permissionCheck1 = ContextCompat.checkSelfPermission(this, Manifest.permission.READ_CONTACTS);
int permissionCheck2 = ContextCompat.checkSelfPermission(this, Manifest.permission.WRITE_CONTACTS);
if (permissionCheck != PackageManager.PERMISSION_GRANTED && permissionCheck1 != PackageManager.PERMISSION_GRANTED && permissionCheck2 != PackageManager.PERMISSION_GRANTED) {
    ActivityCompat.requestPermissions(this, new String[]{android.Manifest.permission.READ_PHONE_STATE}, 1);
    ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.READ_CONTACTS}, 2);
    ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.WRITE_CONTACTS}, 3);

} else {
    TelephonyManager tMgr = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
    mPhoneNumber = tMgr.getLine1Number();
}

我知道我没有这些权限，因为我收到如下错误消息：

java.lang.SecurityException: Permission Denial: opening provider com.android.providers.contacts.ContactsProvider2 from ProcessRecord{95e4cb4 30797:com.example.ortel.tagnet/u0a217} (pid=30797, uid=10217) requires android.permission.READ_CONTACTS or android.permission.WRITE_CONTACTS

另外：它没有请求我的许可来访问 READ_CONTACTS 和 WRITE_CONTACTS。

有什么问题？

Answer 1

您正在使用 && 而不是 ||。就目前而言，如果您只持有三者之一，则不会要求任何运行时权限。

此外，您正在调用 requestPermissions() 三次。使用您需要的任何权限调用一次。 new String[] 创建一个字符串数组，它可以包含您想要的所有三个权限名称。

Answer 2

如果你有 10 个权限，你会把你的代码再扩展 20 行吗？不！

你有两种方法

按照正确的方式请求许可。我正在发布我的代码片段，将此代码复制到您的 Base Activity class.
或者你使用RxPermissions。如果您是 Android.

这是我的代码片段。

String[] permissions = {Manifest.permission.READ_PHONE_STATE, Manifest.permission.READ_CONTACTS, Manifest.permission.WRITE_CONTACTS};

        getBulkPermissions(permissions, new RequestPermissionAction() {
            @Override
            public void permissionDenied() {
                // TODO: 5/27/2018 handle permission deny 
            }

            @Override
            public void permissionGranted() {
                // TODO: 5/27/2018 you code do further operations 
            }
        });

能再简单点吗？

现在您可以将此代码放在基础 Activity class 中并在您需要的任何地方使用。或者如果您在其他地方不需要它，请输入您当前的 class。

RequestPermissionAction onPermissionCallBack;
private final static int REQUEST_BULK_PERMISSION = 3006;

private boolean checkBulkPermissions(String[] permissions) {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
        for (String permission : permissions) {
            if (checkSelfPermission(permission) != PackageManager.PERMISSION_GRANTED) {
                return false;
            }
        }
        return true;
    } else {
        return true;
    }
}

public void getBulkPermissions(String[] permissions, RequestPermissionAction onPermissionCallBack) {
    this.onPermissionCallBack = onPermissionCallBack;
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
        if (!checkBulkPermissions(permissions)) {
            requestPermissions(permissions, REQUEST_BULK_PERMISSION);
            return;
        }
    }
    if (onPermissionCallBack != null)
        onPermissionCallBack.permissionGranted();
}

@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
        if (onPermissionCallBack != null)
            onPermissionCallBack.permissionGranted();
    } else if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_DENIED) {
        if (onPermissionCallBack != null)
            onPermissionCallBack.permissionDenied();
    }
}

public interface RequestPermissionAction {
    void permissionDenied();
    void permissionGranted();
}
