Android 外部 PDF 渲染立即关闭

Question

I'm trying to externally render a PDF from my Android app. My code looks like this

val file = File(<path-to-pdf>)
val target = Intent(Intent.ACTION_VIEW)
target.setDataAndType(Uri.fromFile(file), "application/pdf")
target.flags = Intent.FLAG_ACTIVITY_NO_HISTORY
val intent = Intent.createChooser(target, "Open With")
intent.flags = Intent.FLAG_ACTIVITY_NEW_TASK
try {
      context.startActivity(intent)
} catch (e: ActivityNotFoundException) {
      Log.e(e.message)
}

Whenever this runs on certain devices (so far observed on Pixel 2), the external reader launches, and closes immediately. Solution suggested here did not work.

This doesn't work on some phone using the default Drive PDF Viewer . Try using an alternative PDF viewer using the app picker.
