Question

嘿我正在尝试请求存储访问权限，我注意到在我的其他手机中有android 5.0的权限请求崩溃应用程序。我应该怎么做才能在没有崩溃这个Android版本的应用程序的情况下请求权限，以及我应该从哪个Android版本开始？

这是询问权限的代码：

  int MY_PERMISSIONS_REQUEST_READ_EXTERNAL_STORAGE = 0;
    if (checkSelfPermission(Manifest.permission.READ_EXTERNAL_STORAGE)
        != PackageManager.PERMISSION_GRANTED) {

    // Should we show an explanation?
    if (shouldShowRequestPermissionRationale(
            Manifest.permission.READ_EXTERNAL_STORAGE)) {
        // Explain to the user why we need to read the contacts
    }

    requestPermissions(new String[]{Manifest.permission.READ_EXTERNAL_STORAGE},
            MY_PERMISSIONS_REQUEST_READ_EXTERNAL_STORAGE);

    // MY_PERMISSIONS_REQUEST_READ_EXTERNAL_STORAGE is an
    // app-defined int constant that should be quite unique

    return;
}

动态权限需要API 23或更高版本，因此您可以在条件检查正在运行的API的版本中包装代码。

if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
    int MY_PERMISSIONS_REQUEST_READ_EXTERNAL_STORAGE = 0;
    if(checkSelfPermission(Manifest.permission.READ_EXTERNAL_STORAGE)
        != PackageManager.PERMISSION_GRANTED) {

        // Should we show an explanation?
        if(shouldShowRequestPermissionRationale(
            Manifest.permission.READ_EXTERNAL_STORAGE)) {
            // Explain to the user why we need to read the contacts
        }

        requestPermissions(new String[]{Manifest.permission.READ_EXTERNAL_STORAGE},
                MY_PERMISSIONS_REQUEST_READ_EXTERNAL_STORAGE);

        // MY_PERMISSIONS_REQUEST_READ_EXTERNAL_STORAGE is an
        // app-defined int constant that should be quite unique

        return;
    }
}

我应该从哪个api请求权限？
