在 android 中共享 apk

Question

我正在尝试借助按钮共享 apk，它在昨天之前工作正常，但现在当我按下共享 apk 按钮时，应用程序崩溃了，我不知道它出了什么问题，但在运行选项卡显示下面 java 代码的最后一行有问题。

这是java代码


    btnShareApk.setOnClickListener (new View.OnClickListener ( ) {
                @Override
                public void onClick(View v) {
                    ApplicationInfo applicationInfo = getApplicationContext ().getApplicationInfo ();
                    String apkPath = applicationInfo.sourceDir;
                    Intent intent2 = new Intent (Intent.ACTION_SEND);
                    intent2.setType ("application/vnd.android.package-archive");
                    intent2.putExtra (Intent.EXTRA_STREAM, Uri.fromFile (new File (apkPath) ));
                    startActivity (Intent.createChooser (intent2,"Share Apk via"));
                }
            });

这是xml代码

<Button
            android:id="@+id/btnShareApk"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_margin="20dp"
            android:layout_marginStart="10dp"
            android:background="@drawable/rounded_button_green"
            android:text="Share Apk"

            android:textColor="@color/colorAccent"
            android:textSize="20sp"
            android:textStyle="bold" />

这是来自运行选项卡的日志

感谢任何形式的帮助

Answer 1

尝试将 apk 文件复制到您的应用程序缓存文件夹，然后使用 FileProvider.getUriForFile 将 File 解析为 Uri。

Answer 2

尝试将其添加到 onCreate

StrictMode.VmPolicy.Builder builder = new StrictMode.VmPolicy.Builder();
StrictMode.setVmPolicy(builder.build());
builder.detectFileUriExposure();

您可以使用 Intent 分享您的应用。喜欢：

Intent sharingIntent = new Intent(intent.ACTION_SEND);
