Android动态权限请求

Android动态权限请求：

public static boolean isPermissions = false;//是否获得全部权限。

public static String[] permissions = {android.Manifest.permission.INTERNET,
        android.Manifest.permission.READ_PHONE_STATE,
        android.Manifest.permission.ACCESS_COARSE_LOCATION,
        android.Manifest.permission.ACCESS_FINE_LOCATION,
        android.Manifest.permission.WRITE_EXTERNAL_STORAGE,
        android.Manifest.permission.ACCESS_NETWORK_STATE,
        android.Manifest.permission.CHANGE_NETWORK_STATE,
        android.Manifest.permission.ACCESS_COARSE_LOCATION,
        android.Manifest.permission.READ_EXTERNAL_STORAGE//,
        //android.Manifest.permission.BIND_ACCESSIBILITY_SERVICE
};//所需要申请的的权限列表

    public static void CheckPermissions()
    {
        // 1. 申请权限
        // 首先判断 SDK 版本，是否大于等于 6.0
        if (Build.VERSION.SDK_INT >= 23) {
            int id = 0;
            int checkCallPhonePermission = 0;

            List<String> notGrantedList = new ArrayList<>();
            for(String permission: permissions) {
                // 检查是否已授权
                checkCallPhonePermission = app.checkSelfPermission(permission);
                if (checkCallPhonePermission != PackageManager.PERMISSION_GRANTED) {
                    notGrantedList.add(permission);
                }

            }
            if(notGrantedList.size() > 0){
                String[] notGrantedArray = new String[notGrantedList.size()];
                notGrantedList.toArray(notGrantedArray);
                // 请求用户授权
                app.requestPermissions(notGrantedArray, id);
            }else{
                // 如果不需要用户授权，直接执行后面的代码
                //createMethod();
                if(notGrantedList.size() <= 0)
                {
                    isPermissions = true;
                }
            }
        }else{
            // 如果SDK小于6.0，无需动态申请权限
            //createMethod();
        }
    }
    @Override
    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
        super.onRequestPermissionsResult(requestCode, permissions, grantResults);

        if(requestCode == 0){
            int grantCount = 0;
            for(int grant : grantResults){
                if(grant == PackageManager.PERMISSION_GRANTED){
                    grantCount ++;
                }
            }
            if(grantCount == grantResults.length){
                // 权限获取成功，执行后面的代码

                isPermissions = true;
            }else{

                    @Override
                    public void run() {
                        AlertDialog alertDialog = new AlertDialog.Builder(app).setTitle("温馨提示")
                                .setMessage("应用需要相应的权限，否则无法正常使用，请前往应用设置进行授权或返回上一页面。")
                                .setPositiveButton("前往设置", new DialogInterface.OnClickListener() {
                                    @Override

                                        startActivity(intent);
                                    }
                                }).setNegativeButton("返回", new DialogInterface.OnClickListener() {
                                    @Override
                                    public void onClick(DialogInterface dialog, int which) {
//                                        isCreated = false;
//                                        Intent intent = null;
//                                        try {
//                                            intent = new Intent(app, Class.forName(packageName+".MainActivity"));
//                                        } catch (ClassNotFoundException e) {
//                                            e.printStackTrace();

                                        app.finish();
                                        android.os.Process.killProcess(android.os.Process.myPid());
                                        System.exit(0);
                                    }
                                }).setCancelable(false).create();
                        alertDialog.show();
                    }
                });
            }
        }
    }

以上代码为启动时请求权限。
如果在游戏中需要验证权限，就获取isPermissions，如果为true，则权限全部验证通过，如果为false，则至少有一项没有通过。
如果不想通过这个参数来判断，若要重新验证权限是否通过，则再用如下代码判断。：

public static boolean CheckPermissionsByGame()
{
    if (Build.VERSION.SDK_INT >= 23)
    {
        int id = 0;
        int checkCallPhonePermission = 0;

        List<String> notGrantedList = new ArrayList<>();
        for (String permission : permissions)
        {
            // 检查是否已授权
            checkCallPhonePermission = app.checkSelfPermission(permission);
            if (checkCallPhonePermission != PackageManager.PERMISSION_GRANTED)
            {
                notGrantedList.add(permission);
            }

        }
        if (notGrantedList.size() > 0)
        {
            String[] notGrantedArray = new String[notGrantedList.size()];
            notGrantedList.toArray(notGrantedArray);
            return false;
            // 请求用户授权
            //requestPermissions(notGrantedArray, id);
        }
        else
            {
            // 如果不需要用户授权，直接执行后面的代码
            //createMethod();
            if (notGrantedList.size() <= 0)
            {
                isPermissions = true;
            }
        }
    }
    else {
        // 如果SDK小于6.0，无需动态申请权限
        //createMethod();
    }
    return true;
}
