Programatically install apk from assets folder in android

Question

I am trying to install apk programatically from assets folder but not success, Please help me. I am using following code for that. thank you.

Intent intent = new Intent(Intent.ACTION_VIEW)
.setData(Uri.parse("file:///android_asset/youtuberanjit.apk"))
.setType("application/vnd.android.package-archive");
startActivity(intent);

Akash first copy the apk file from assets to sdcard and then install apk from sdcard . I think this is the only way to do this. — Chirag, Oct 01 '12 at 12:26
@Chirag Raval : SDCARD not available in my device, I want to install apk directly from asset folder to device. Without use of sdcard... — Ranjitsingh Chandel, Oct 01 '12 at 12:29
The asset directory is just an unstructured hierarchy of files, allowing you to put anything you want there and later retrieve as raw byte streams. — Chirag, Oct 01 '12 at 12:31
ok but, without using sdcard is this possible to install apk. Can I use another thing or technique replace with sdcard. — Ranjitsingh Chandel, Oct 01 '12 at 12:35
@Chirag Raval : Ok i will try this way... If you have helpful link for that so plz share with me. — Ranjitsingh Chandel, Oct 01 '12 at 12:40
Problem solved... first I saved apk in data/data/mypkg/myapk.apk programatically. And then start installation of apk using intent. Thank you very much for all. — Ranjitsingh Chandel, Oct 02 '12 at 12:22

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) { }

Is this possible without using sdcard ? – Ranjitsingh Chandel Oct 01 '12 at 12:38
or you can do it this way intent.setDataAndType(Uri.fromFile("file:///android_asset/myapk.apk"), "application/vnd.android.package-archive"); I have not tested this! – skygeek Oct 01 '12 at 12:42

this one is correct intent.setDataAndType(Uri.fromFile(new File("file:///android_asset/myapk.apk")), "application/vnd.android.package-archive"); – skygeek Oct 01 '12 at 12:44
its regarding to your .apk file. cross check version code name package name and all – skygeek Oct 01 '12 at 13:08
Using this code first I saved apk in data/data/my_application_pkg/myapk.apk Then install apk from this place using INTENT. Is successfully done. Thank you very much for all answers and reply... – Ranjitsingh Chandel Oct 02 '12 at 12:25

Copy the apk file into assets folder.

try this method it worked for me ..........

private void launchComponent(String packageName, String name) { 

  // Name should be starting activity complete name with package name
        Intent launch_intent = new Intent("android.intent.action.MAIN");
        launch_intent.addCategory("android.intent.category.LAUNCHER");
        launch_intent.setComponent(new ComponentName(packageName, name));
        launch_intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

        this.startActivity(launch_intent);
    }
