我正在制作聊天应用程序,并希望通过意向分享应用程序。解决这个问题的办法不多请帮忙。这是我的代码,但它在启动活动中抛出错误

navigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
        @SuppressLint("NonConstantResourceId")
        @Override
        public boolean onNavigationItemSelected(@NonNull MenuItem menuItem) {
            switch (menuItem.getItemId()){

                case R.id.share :

                    ApplicationInfo api = getApplicationContext().getApplicationInfo();
                    String apkPatch = api.sourceDir;

                    Intent intent = new Intent(Intent.ACTION_SEND);
                    intent.setType("application/vnd.android.package-archive");
                    intent.putExtra(Intent.EXTRA_STREAM,Uri.fromFile(new File(apkPatch)));
                    intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

                    startActivity(Intent.createChooser(intent, "ShareVia"));

                    Toast.makeText(NavigationActivity.this, "shareVia", Toast.LENGTH_SHORT).show();
                case R.id.aboutus :
                    Toast.makeText(getApplicationContext(), "aboutUs", Toast.LENGTH_SHORT).show();

            }

            return true;
        }
    });

这是运行屏幕中的错误

问题是,对于新的api,文件uri方案与旧api的方案不同。所以使用 new File(apkPatch) 将为较新的API引发此异常。
所以,你可以把绳子传给 Uri.parse ,而不是 File 为了解决这个问题而不是使用 Uri.fromFile 因此,请替换以下代码行:

intent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(new File(apkPatch)));

使用:

intent.putExtra(Intent.EXTRA_STREAM, Uri.parse(apkPatch));

我已经尝试过你的解决方案,它的工作非常好,但apk文件名是base.apk,但我想在那里我的应用程序名(聊天框)而不是基地
现在要更改apk文件名,请在下面添加到intent

intent.putExtra(Intent.EXTRA_SUBJECT, "Chat Box.apk");
