Question

我使用此代码将应用的APK文件发送到另一台设备。它适用于android 2.3.3，但不适用于android 4 +。

问题出在哪里？

我已经记录了getpackageCodePath()并且它在android 4+上返回了APK文件，但是整个代码都不起作用，当蓝牙启动时，它什么也没发送。

ArrayList<Uri> uris = new ArrayList<Uri>();
Intent sendIntent = new Intent(Intent.ACTION_SEND_MULTIPLE);
sendIntent.setType("application/vnd.android.package-archive");
uris.add(Uri.parse(getApplication().getPackageCodePath()));
sendIntent.putParcelableArrayListExtra(Intent.EXTRA_STREAM, uris);
startActivity(Intent.createChooser(sendIntent, null));

Answer 1

我使用下面的代码发送apk。它的工作原理

try{
    ArrayList<Uri> uris = new ArrayList<Uri>();
    Intent sendIntent = new Intent(Intent.ACTION_SEND_MULTIPLE);
    sendIntent.setType("application/*");
    uris.add(Uri.fromFile(new File(getApplicationInfo().publicSourceDir)));
    sendIntent.putParcelableArrayListExtra(Intent.EXTRA_STREAM, uris);
    startActivity(Intent.createChooser(sendIntent, null));

}catch(Exception e){}

Answer 2

更改行：

uris.add(Uri.parse(getApplication().getPackageCodePath()));

到

uris.add(Uri.fromFile(new File(getApplicationInfo().publicSourceDir)));

它应该适用于所有4.x设备。或者你也可以这样做：

ApplicationInfo app=getPackageManager().getApplicationInfo("packageName", 0);                       
uris.add(Uri.fromFile(new File(app.publicSourceDir)));

上述两种方式都适合我。

Answer 3

您可以使用getApplicationInfo().publicSourceDir代替getApplication().getPackageCodePath()来获取应用APK的路径，然后在ACTION_SEND Intent中使用该路径通过蓝牙发送文件。< / p>

InputStream in = null;
            OutputStream out = null;
            File apkPublicFilePath = new File(
                    Environment
                            .getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS),
                    "myapk.apk");
            try {

                in = getResources().openRawResource(R.raw.myapk);
                out = new FileOutputStream(apkPublicFilePath);
                byte[] buffer = new byte[1024];
                int length;
                while ((length = in.read(buffer)) > 0) {
                    out.write(buffer, 0, length);
                }

                // Close the streams
                out.flush();
                out.close();
                in.close();
            } catch (IOException e) {
                Log.d(TAG, "Error in copy files");
            }

            Intent sendIntent = new Intent();
            sendIntent.setAction(Intent.ACTION_SEND);
            sendIntent.putExtra(Intent.EXTRA_STREAM,

            Uri.fromFile(apkPublicFilePath.getAbsoluteFile()));
            try {
                sendIntent.setType("application/vnd.android.package-archive");
                startActivity(Intent.createChooser(
                        sendIntent,
                        PersianReshape.reshape(getResources().getString(
                                R.string.msg_send))));
            } catch (Exception e) {
                sendIntent.setType("*/*");
                startActivity(Intent.createChooser(
                        sendIntent,
                        PersianReshape.reshape(getResources().getString(
                                R.string.msg_send))));
            }

Answer 5

我希望它有效：

// Get current ApplicationInfo to find .apk path
ApplicationInfo app = getApplicationContext().getApplicationInfo();
String filePath = app.sourceDir;

Intent intent = new Intent(Intent.ACTION_SEND);

// MIME of .apk is "application/vnd.android.package-archive".
// but Bluetooth does not accept this. Let's use "*/*" instead.
intent.setType("*/*");

// Only use Bluetooth to send .apk
intent.setPackage("com.android.bluetooth");

// Append file and send Intent
intent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(new File(filePath)));
startActivity(Intent.createChooser(intent, "Share app"));

Answer 6

ArrayList<Uri> uris = new ArrayList<Uri>();
    Intent sendIntent = new Intent(Intent.ACTION_SEND_MULTIPLE);
sendIntent.setType("*/*");
uris.add(Uri.fromFile(new File(getApplicationInfo().publicSourceDir)));
sendIntent.putParcelableArrayListExtra(Intent.EXTRA_STREAM, uris);
startActivity(Intent.createChooser(sendIntent, null));
