Android 6.0 运行时请求权限

从 Android 6.0（API 级别 23）开始，用户开始在应用运行时向其授予权限，而不是在应用安装时授予。

private void initPermission() {
    String permissions[] = {
        Manifest.permission.RECORD_AUDIO,
        Manifest.permission.ACCESS_NETWORK_STATE,
        Manifest.permission.INTERNET,
        Manifest.permission.READ_PHONE_STATE,
        Manifest.permission.WRITE_EXTERNAL_STORAGE
        };
        ArrayList<String> toApplyList = new ArrayList<String>();
        for (String perm : permissions) {
            if (PackageManager.PERMISSION_GRANTED != ContextCompat.checkSelfPermission(this, perm)) {
                toApplyList.add(perm);
                //进入到这里代表没有权限.
            }
    }
    String tmpList[] = new String[toApplyList.size()];
    if (!toApplyList.isEmpty()) {
        ActivityCompat.requestPermissions(this, toApplyList.toArray(tmpList), 123);
    }
}

@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
    // 此处为Android 6.0以上动态授权的回调，用户自行实现。
}
