Select 图片并将结果发送到 android 工作室中的另一个 activity 保持强制关闭

Question

所以，我遇到了一个问题，每次我选择一个图像时，应用程序都会强制关闭，当然选择的图像无法发送到另一个 activity，但是对于相机 activity 它正在做美好的。这是我的代码

ChooseActivity.kt

 private fun takePhoto() {
    val cameraIntent = Intent(MediaStore.ACTION_IMAGE_CAPTURE)
    startActivityForResult(cameraIntent, CAMERA_REQUEST)
  }

  private fun chooseLibrary() {
    val libraryIntent = Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI)
    startActivityForResult(libraryIntent, LIBRARY_REQUEST)

override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
    if (resultCode != Activity.RESULT_OK) return

    when (requestCode) {
      CAMERA_REQUEST -> {
        val thumbnail: Bitmap = data!!.getParcelableExtra("data")
        val intent = Intent(this@ChooseActivity, StillImageActivity::class.java)
        intent.putExtra("bitmap", thumbnail)
        startActivity(intent)
        finish()
      }
      LIBRARY_REQUEST -> {
        val uri: Uri = data!!.getData()!!
        val bitmap = MediaStore.Images.Media.getBitmap(this.contentResolver, uri)
        val intent = Intent(this@ChooseActivity, StillImageActivity::class.java)
        intent.putExtra("bitmap", bitmap)
        startActivity(intent)
        finish()
      }
    }
  }

  companion object {
    private const val CAMERA_REQUEST = 10
    private const val LIBRARY_REQUEST = 20
  }
}

最初，我将 CAMERA_REQUEST 中的代码用于 LIBRARY_REQUEST 除了变量，但它不起作用，所以我决定寻找任何修复，但仍然没有运气

我使用此代码在另一个 activity

中接收结果

StillImageActivity.kt

fun getImage() {
    val extras = intent.extras
    if (extras != null) {
      val bitmap = extras["bitmap"] as Bitmap
      if (bitmap != null) {
        imagePreview?.setImageBitmap(bitmap)

        classifyImage(bitmap)
      }
    }
  }

我把它作为一个函数，因为我想在这里调用它以便对图像进行分类。这是一个图像分类应用程序

// Setup image classifier.
    try {
      classifier = ImageClassifier(this)
    } catch (e: FirebaseMLException) {
      textView?.text = getString(R.string.fail_to_initialize_img_classifier)
    }

    // Classify the sent image
    getImage()
  }

这个问题有什么可能的解决办法吗？我希望从图库中选择的图像是使用此功能接收的，因此它会像相机一样立即分类activity，或者如果有更好的解决方案，它将有很大帮助。

这是 logcat 错误

Answer 1

您收到的错误是 android.os.TransactionTooLargeException

当您传递过多数据时，可能会发生这种情况。

您可以使用静态字段或单例在活动之间共享数据，请参阅：http://developer.android.com/guide/faq/framework.html#3 - Another way, which goes out of the scope of this question but can easily be found by searching here on SO is by passing the data using SharedPreferences, e.g.:

有一个工具可以用来找出发生这种情况的地方，它叫做： https://github.com/guardian/toolargetool

在出现这个错误的activity处，你应该添加outState.clear();

例如

@Override
protected void onSaveInstanceState(Bundle outState) {
    super.onSaveInstanceState(outState);
    //Clear the Activity's bundle
    outState.clear();
}

Select 图片并将结果发送到 android 工作室中的另一个 activity 保持强制关闭

Select image and sent the result to another activity in android studio keep force closing

android

uri

bitmap

android-intent
