安卓6.0权限

写Android的功能Api给别人用，自己测了很多次都没问题，结果跑到别人手机上就闪退，心塞了半天，后来看到Log发现是手机权限问题。

于是想起之前写过一个内存写入测试Apk，也遇到过类似的问题。在5.0平台上能够正常运行，放到6.0的手机上就会出现权限问题闪退。

直接贴代码

private void startAuthorize(String[] permissions) {
    //android 6.0以上如果授权失败会finish掉页面
    if (Build.VERSION.SDK_INT >= 23) {
        ArrayList<String> deniedPermissions = new ArrayList<String>();
        for (int i = 0; permissions != null && i < permissions.length; i++) {
            String permission = permissions[i];
            if (checkSelfPermission(permission) != PackageManager.PERMISSION_GRANTED) {
                deniedPermissions.add(permission);
            }
        }
        int count = deniedPermissions.size();
        if (count > 0) {
            String[] array = new String[count];
            deniedPermissions.toArray(array);
            requestPermissions(array, PERMISSION_REQ);
        }
    }
}

@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    switch (requestCode) {
        case PERMISSION_REQ:
            for (int i = 0; i < grantResults.length; i++) {
                if (grantResults[i] == PackageManager.PERMISSION_DENIED) {
                    Toast.makeText(GetAuthorizationActivity.this, "您需要授权才能使用", Toast.LENGTH_LONG).show();
                    return;
                }
            }
            break;
    }

}
