首页的更新弹窗多个

前提：当App没有赋予权限，并且有更新弹窗的时候，去设置给予权限，然后回来，弹窗是2个或者3个。

解决方式：（缺点：回来的时候，可能有闪动的界面，清除多余的界面）

     if (null != savedInstanceState) {
            Intent intent = new Intent(this, MainActivity.class);
            intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
            startActivity(intent);
        }

原来定位的是这么设置：

        AlertDialog.Builder bd = new HuzAlertDialog.Builder(MainActivity.this);
        bd.setTitle("温馨提示");
        bd.setMessage("您的定位没有开启，为了不影响您正常使用，请将定位开启");
        bd.setPositiveButton("立即开启", new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog, int which) {
                Intent localTntent = new Intent();
                localTntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                if (Build.VERSION.SDK_INT >= 9) {
                    localTntent.setAction("android.settings.APPLICATION_DETAILS_SETTINGS");
                    localTntent.setData(Uri.fromParts("package", getPackageName(), null));
                } else if (Build.VERSION.SDK_INT <= 8) {
                    localTntent.setAction(Intent.ACTION_VIEW);
                    localTntent.setClassName("com.android.settings", "com.android.settings.InstalledAppDetails");
                    localTntent.putExtra("com.android.setting.ApplicationPkgName", getPackageName());
                }
                startActivity(localTntent);
            }
        });
        bd.setNeutralButton("残忍拒绝", new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog, int which) {
            }
        });
        bd.show();

最好不要跳到设置去给予权限，在当前的界面设置权限：

 if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
            // 判断权限是否拥有
            if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED||
                    ActivityCompat.checkSelfPermission(this, Manifest.permission.WRITE_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED) {
                LogUitl.e("=====onRequestPermissionsResult=====:未被授予，需要申请");
                requestPhotoPermissions();
            }
        }

   private static String[] PERMISSIONS_PHOTO = {Manifest.permission.ACCESS_COARSE_LOCATION, Manifest.permission.WRITE_EXTERNAL_STORAGE};
    private static final int REQUEST_PHOTO_SYN = 3;
    private void requestPhotoPermissions() {
        if (ActivityCompat.shouldShowRequestPermissionRationale(this, Manifest.permission.ACCESS_COARSE_LOCATION)||
                ActivityCompat.shouldShowRequestPermissionRationale(this, Manifest.permission.WRITE_EXTERNAL_STORAGE)) {
            // 如果是第二次申请，需要向用户说明为何使用此权限，会带出一个不再询问的复选框！
            LogUitl.e("=====onRequestPermissionsResult====:如果是第二次申请，需要向用户说明为何使用此权限，会带出一个不再询问的复选框");

            android.support.v7.app.AlertDialog.Builder builder=new android.support.v7.app.AlertDialog.Builder(MainActivity.this);
            builder.setMessage("只有定位和存储权限，才可以正常使用该APP！");
            builder.setTitle("定位和存储权限");
            builder.setPositiveButton("前往设置", new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int which) {
                    ActivityCompat.requestPermissions(MainActivity.this, PERMISSIONS_PHOTO,REQUEST_PHOTO_SYN);
                }
            });
            builder.setNegativeButton("残忍拒绝", new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int which) {
                    dialog.dismiss();
                }
            });
            builder.create().show();
        } else {
            LogUitl.e("=====onRequestPermissionsResult=====:第一次申请此权限，直接申请");
            ActivityCompat.requestPermissions(this, PERMISSIONS_PHOTO, REQUEST_PHOTO_SYN);
        }
    }

    @Override
    public void onRequestPermissionsResult(int requestCode,String[] permissions,int[] grantResults) {
        switch (requestCode){
            case REQUEST_PHOTO_SYN:
                LogUitl.e("=====onRequestPermissionsResult=====:这里有个多权限的检查，需要检查每一个权限是否都被授权了");
                if (PermissionUtil.verifyPermissions(grantResults)) {
//                    showPicturePicker();
                    LogUitl.e("=====onRequestPermissionsResult=====:true，所有权限已经被授予");
                } else {
                    showToast("定位和存储权限被拒绝,部分功能将不能使用！");
                }
                break;

            default:
                break;
        }
    }
