编程方式安装在/ RES的.apk文件/生 [英] Programatically install .apk file located in /res/raw

问题描述

我已经存储在的apk文件的另一个应用程序在我的/ RES / raw目录，并希望给用户一个提示进行安装。这是我目前的code：

I have stored a .apk file for another app in my /res/raw directory and wish to give the user a prompt to install it. Here's my current code:

Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.fromFile(new File("android.resource://" + getPackageName() + "/res/raw/myapk.apk")), "application/vnd.android.package-archive");
startActivity(intent);

然而，当意图运行，我得到一个解析错误：有一个问题解析包

该.apk文件文件是当我运行其他应用程序通过月食在/ bin目录下创建的。

The .apk file is the one created by eclipse in the /bin directory when I run the other application.

我将如何完成这一正确纲领性本地安装？

How would I accomplish this programmatic local install correctly?

推荐答案

我想它了。最后我把我的.apk文件中的/资产目录和编程复制它的地方，我从它安装在SD卡。这是我的code：

I figured it out. I ended up putting my .apk file in the /assets directory and copying it programatically to the sd card where I installed it from. Here's my code:

AssetManager assetManager = getAssets();
InputStream in = null;
OutputStream out = null;
try {
    in = assetManager.open("myapk.apk");
    out = new FileOutputStream("/sdcard/myapk.apk");
    byte[] buffer = new byte[1024];
    int read;
    while((read = in.read(buffer)) != -1){
        out.write(buffer, 0, read);
    }
    in.close();
    in = null;
    out.flush();
    out.close();
    out = null;
    Intent intent = new Intent(Intent.ACTION_VIEW);
    intent.setDataAndType(Uri.fromFile(new File("/sdcard/myapk.apk")), "application/vnd.android.package-archive");
    startActivity(intent);
}catch(Exception e){
    // deal with copying problem
}
