Question

对于Android 6.0版本，我为android 6.0添加了运行时权限。但如果用户拒绝该权限意味着我的应用程序崩溃。我在下面附上了我的代码。所以任何人都帮助我。提前谢谢。

我的代码：

 private static final String[] INITIAL_PERMS={
            Manifest.permission.ACCESS_FINE_LOCATION,
            Manifest.permission.READ_CONTACTS,Manifest.permission.ACCESS_COARSE_LOCATION,Manifest.permission.READ_PHONE_STATE,

            Manifest.permission.READ_CALL_LOG,Manifest.permission.WRITE_CALL_LOG,Manifest.permission.WRITE_EXTERNAL_STORAGE,
            Manifest.permission.READ_CONTACTS, Manifest.permission.SEND_SMS,Manifest.permission.RECEIVE_SMS,

            Manifest.permission.CAMERA,Manifest.permission.READ_SMS
    };
 if(Build.VERSION.SDK_INT >= 23 ){


            if (!canAccessLocation() || !canAccessLocation_1() || !canAccessPhone() || !canAccessContacts() || !canAccessStorage() || !canAccessContacts1()
                    || !canAccessSms() || !canAccessSms1() || !canAccessSms2() || !canAccessCamera()) {
                ActivityCompat.requestPermissions(SplashActivity.this, INITIAL_PERMS, INITIAL_REQUEST);
            }
        }
        else if (Build.VERSION.SDK_INT < 23) {


            //not a marshamallow
        }

 @Override
    public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {


        switch(requestCode) {
            case REQUEST_CAMERA:
                if (canAccessCamera()) {
                    doCameraThing();
                }
                else {
                    bzzzt();
                }
                break;

            case REQUEST_CONTACTS:

                }
                else {

                }
                break;

Answer 1

您最好的选择是捕获请求权限的输出。您可以通过检查grantResults参数获取已授予结果的数量来执行此操作。

如果您没有获得足够的金额，您可以选择以下两个选项之一（从用户体验的角度来看）：

再次询问用户权限
显示一条消息，说明用户无权启动应用程序。

（显然，这两种情况不必相互排斥）。

你可以通过以下方式实现这一点：

@Override
public void onRequestPermissionsResult(int requestCode,
        String permissions[], int[] grantResults) {
    switch (requestCode) {
        case MY_PERMISSIONS_REQUEST_READ_CONTACTS: {
            // If request is cancelled, the result arrays are empty.
            if (grantResults.length > 0
                && grantResults[0] == PackageManager.PERMISSION_GRANTED) {

                // permission was granted, yay! Do the
                // contacts-related task you need to do.

            } else {

                // permission denied, boo! Disable the
                // functionality that depends on this permission.
            }
            return;
        }

        // other 'case' lines to check for other
        // permissions this app might request
    }
}

可以在Android docs for Requesting Permissions at Runtime找到更多信息。

Answer 2

    int permissions_All = 1;
    String[] Permissions = {Manifest.permission.RECEIVE_SMS, 
    Manifest.permission.READ_SMS 
     };
    if (!hasPermissions(this, Permissions)) {
        ActivityCompat.requestPermissions(this, Permissions, permissions_All);
    }
}

public static boolean hasPermissions(Context context, String... Permissions) {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M && Permissions != null) {
        for (String Permission : Permissions) {
            if (ActivityCompat.checkSelfPermission(context, Permission) != PackageManager.PERMISSION_GRANTED) {
                return false;
            }
        }
    }

在活动的onCreate方法中写下所有这些代码提及清单文件中的所有权限，并在字符串数组中提及它们

android 6.0中的android运行时权限？
