我正在開發(fā)一個(gè)帶有嵌入式二維碼閱讀器的應(yīng)用程序，在掃描代碼之后，我必須使用從二維碼中獲取的參數(shù)啟動(dòng)另一個(gè)活動(dòng)（名為 CodaActivity.class）。我從此處找到的教程開始：( https://www.androidtutorialonline.com/android-qr-code-scanner/ ) 并嘗試根據(jù)我的需要對其進(jìn)行自定義。這是 QRCodeScannerActivity 的代碼：import android.content.DialogInterface;import android.content.Intent;import android.content.pm.PackageManager;import android.net.Uri;import android.os.Build;import android.os.Bundle;import android.support.v4.app.ActivityCompat;import android.support.v4.content.ContextCompat;import andoid.support.v7.app.AlertDialog;import android.support.v7.app.AppCompatActivity;import android.util.Log;import android.widget.Toast;import com.google.zxing.Result;import me.dm7.barcodescanner.zxing.ZXingScannerView;import static android.Manifest.permission.CAMERA;public class QrCodeScannerActivity extends AppCompatActivity implements ZXingScannerView.ResultHandler {    private static final int REQUEST_CAMERA = 1;    private ZXingScannerView mScannerView;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        mScannerView = new ZXingScannerView(this);        setContentView(mScannerView);        int currentapiVersion = android.os.Build.VERSION.SDK_INT;        if (currentapiVersion >= android.os.Build.VERSION_CODES.M) {            if (checkPermission()) {                Toast.makeText(getApplicationContext(), "Permission already granted", Toast.LENGTH_LONG).show();            } else {                requestPermission();            }        }    }           }}但是在我掃描二維碼后（當(dāng)然是用物理設(shè)備），調(diào)試器退出并顯示以下消息：I/art: Object allocation is busy now, so prior to grow the heap. New heap size is 33 MBI/art: current process_level is : 0I/art: current process_level is : 0I/art: current process_level is : 0I/art: current process_level is : 0I/art: current process_level is : 0I/Process: Sending signal. PID: 8310 SIG: 9Application terminated.手機(jī)中的應(yīng)用程序仍然保持運(yùn)行狀態(tài)，但會進(jìn)行不同的活動(dòng)。為什么？以及為什么我沒有錯(cuò)誤！感謝您的回答
