因为无法获取真实路径，我应该如何使用libaums安装U盘中的apk，copy？不能直接安装吗？

是的，复制到内部存储然后使用FileProvider获取Uri

好的，谢谢

可直接在u盘安装apk!!! 系统安装方法实际也是先通过读写IO流copy apk,那么我们也可以通过new UsbFileInputStream(UsbFile)获取到IO流，再在系统方法基础上替换获取IO流的部分即可.

代码如下： @RequiresApi(api = Build.VERSION_CODES.LOLLIPOP) public static void install28UsbFile(Context context, UsbFile apkFile,InstallCallback callback) { PackageInstaller packageInstaller = context.getPackageManager().getPackageInstaller(); PackageInstaller.SessionParams sessionParams = new PackageInstaller.SessionParams(PackageInstaller.SessionParams.MODE_FULL_INSTALL); sessionParams.setSize(apkFile.getLength());

    int sessionId = createSession(packageInstaller, sessionParams);
    if (sessionId != -1) {
        boolean copySuccess = copyInstallUsbFile(packageInstaller, sessionId, apkFile);
        if (copySuccess) {
            execInstallCommand(context, packageInstaller, sessionId,apkFile.getName());
        }else {
            if (callback !=null)
                callback.onFailure(apkFile.getName());
        }
    }else {
        if (callback !=null)
            callback.onFailure(apkFile.getName());
    }
}



@RequiresApi(api = Build.VERSION_CODES.LOLLIPOP)
private static boolean copyInstallUsbFile(PackageInstaller packageInstaller,
                                       int sessionId, UsbFile apkFile) {
    InputStream in = null;
    OutputStream out = null;
    PackageInstaller.Session session = null;
    boolean success = false;
    try {
        session = packageInstaller.openSession(sessionId);
        out = session.openWrite("base.apk", 0, apkFile.getLength());
        in = new UsbFileInputStream(apkFile);
        int total = 0, c;
        byte[] buffer = new byte[65536];
        while ((c = in.read(buffer)) != -1) {
            total += c;
            out.write(buffer, 0, c);
        }
        session.fsync(out);
        Log.d(TAG, "streamed " + total + " bytes");
        success = true;
    } catch (IOException e) {
        e.printStackTrace();
    } finally {
        closeQuietly(out);
        closeQuietly(in);
        closeQuietly(session);
    }
    return success;
}



@RequiresApi(api = Build.VERSION_CODES.LOLLIPOP)
private static void execInstallCommand(Context context, PackageInstaller packageInstaller, int sessionId,String apkFilePath) {
    PackageInstaller.Session session = null;
    try {
        session = packageInstaller.openSession(sessionId);
        Intent intent = new Intent(context, InstallResultReceiver.class);
        intent.putExtra("apkFilePath",apkFilePath);
        PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 1, intent, PendingIntent.FLAG_UPDATE_CURRENT);
        session.commit(pendingIntent.getIntentSender());
    } catch (IOException e) {
        e.printStackTrace();
    } finally {
        closeQuietly(session);
    }
}

    } catch (IOException e) {
        e.printStackTrace();
    } finally {

    }
}

这种方式还是复制到临时文件，然后再安装吧？

谢谢，这种方法是可行的，十分感谢
