Android中的授权管理

检查有没有某项权限

 /**
     * 检查用户是否开启权限  Manifest.permission.ACCESS_COARSE_LOCATION
     *
     * @param activity
     */
    public static Boolean checkPermission(Activity activity, String permission) {
        try {
            if (ContextCompat.checkSelfPermission(activity, permission)
                    != PackageManager.PERMISSION_GRANTED) {
                ActivityCompat.requestPermissions(activity, new String[]{permission}, 1);
                return false;
            } else {
                return true;
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
        return false;
    }

权限申请回调

 @Override
    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
        super.onRequestPermissionsResult(requestCode, permissions, grantResults);
        if (requestCode == 1) {
            if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                //同意授权
                stopPublish();
                startPublishRtmp();
            } else {
                //不同意授权
                AllUtils.refuseVoicePermissionsDialog(this);
                finish();
            }
        }
    }

弹窗提示用户去设置权限

/**
     * 用户拒绝了权限申请提醒
     */
    public static void refuseVoicePermissionsDialog(final Context context) {
        //当拒绝了授权后，为提升用户体验，可以以弹窗的方式引导用户到设置中去进行设置
        new AlertDialog.Builder(context)
                .setMessage("权限被禁止，需要开启权限才能使用此功能，请在授权管理或应用程序管理打开，否则无法正常使用")
                .setPositiveButton("设置", new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                        //引导用户到设置中去进行设置
                        Intent intent = new Intent();
                        intent.setAction("android.settings.APPLICATION_DETAILS_SETTINGS");
                        intent.setData(Uri.fromParts("package", context.getPackageName(), null));
                        context.startActivity(intent);
                    }
                })
                .setNegativeButton("取消", null)
                .create()
                .show();
    }
