本文介绍了一个用于Android应用中检查并请求必要权限的方法。通过PackageManager检查READ_EXTERNAL_STORAGE、WRITE_EXTERNAL_STORAGE及RECORD_AUDIO权限的状态，并在缺失时使用ActivityCompat.requestPermissions进行权限请求。

private void  checkPermission()
{
    // 检查权限是否获取（android6.0及以上系统可能默认关闭权限，且没提示）
    PackageManager pm = getPackageManager();
    boolean permission_readStorage = (PackageManager.PERMISSION_GRANTED ==
            pm.checkPermission("android.permission.READ_EXTERNAL_STORAGE", "packageName"));
    boolean permission_writeStorage = (PackageManager.PERMISSION_GRANTED ==
            pm.checkPermission("android.permission.WRITE_EXTERNAL_STORAGE", "packageName"));
    boolean permission_caremera = (PackageManager.PERMISSION_GRANTED ==
            pm.checkPermission("android.permission.RECORD_AUDIO", "packageName"));

    if (!(permission_readStorage && permission_writeStorage && permission_caremera)) {
        ActivityCompat.requestPermissions(AudioRecordActivity.this, new String[]{
                Manifest.permission.READ_EXTERNAL_STORAGE, Manifest.permission.WRITE_EXTERNAL_STORAGE,
                Manifest.permission.RECORD_AUDIO,
        }, 0x01);
    }
}
