绝望 android 分享图片

Question

我想创建将使用 android ACTION_SEND 意图来共享图像的共享按钮。这是我的代码：

from kivy.setupconfig import USE_SDL2


def share(path):
    if platform == 'android':
        from jnius import cast
        from jnius import autoclass
        if USE_SDL2:
            PythonActivity = autoclass('org.kivy.android.PythonActivity')
        else:
            PythonActivity = autoclass('org.renpy.android.PythonActivity')
        Intent = autoclass('android.content.Intent')
        String = autoclass('java.lang.String')
        Uri = autoclass('android.net.Uri')
        File = autoclass('java.io.File')

        shareIntent = Intent(Intent.ACTION_SEND)
        shareIntent.setType('"image/*"')
        imageFile = File(path)
        uri = Uri.fromFile(imageFile)
        shareIntent.putExtra(Intent.EXTRA_STREAM, uri)

        currentActivity = cast('android.app.Activity', PythonActivity.mActivity)
        currentActivity.startActivity(shareIntent)

但它不起作用）它在这一行 shareIntent.putExtra(Intent.EXTRA_STREAM, uri) 中抛出此错误 jnius.jnius.JavaException: Invalid instance of u'android/net/Uri' passed for a u'java/lang/String'。我该如何解决这个问题？

Answer 1

我找到了解决方案。您必须将 uri 转换为 parcelable，然后将其传递给 intent：

parcelable = cast('android.os.Parcelable', uri)
shareIntent.putExtra(Intent.EXTRA_STREAM, parcelable)

Answer 2

此方法适用于 API 24 和最新：

def share(self):
        if platform == 'android':
            from android.storage import primary_external_storage_path
            from jnius import autoclass
            from jnius import cast
            import os
            
            StrictMode = autoclass('android.os.StrictMode')
            StrictMode.disableDeathOnFileUriExposure()
            
            PythonActivity = autoclass('org.kivy.android.PythonActivity')
            
            Intent = autoclass('android.content.Intent')
            String = autoclass('java.lang.String')
            Uri = autoclass('android.net.Uri')
            File = autoclass('java.io.File')

            shareIntent = Intent(Intent.ACTION_SEND)
            shareIntent.setType('"application/pdf"')

            path = os.path.join(primary_external_storage_path(),"test.pdf")

            imageFile = File(path)
            uri = Uri.fromFile(imageFile)
            parcelable = cast('android.os.Parcelable', uri)
            shareIntent.putExtra(Intent.EXTRA_STREAM, parcelable)

            currentActivity = cast('android.app.Activity', PythonActivity.mActivity)
            currentActivity.startActivity(shareIntent)
