从url安装apk

Question

我尝试从URl安装apk,这是我的代码:

Intent promptInstall = new Intent(android.content.Intent.ACTION_VIEW);
promptInstall.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
promptInstall.setDataAndType(Uri.parse("http://10.0.2.2:8081/MyAPPStore/apk/Teflouki.apk"), "application/vnd.android.package-archive" );

startActivity(promptInstall);

但我有这个问题:

05-10 15:09:29.511: ERROR/AndroidRuntime(1668): android.content.ActivityNotFoundException: No Activity found to handle Intent { act=android.intent.action.VIEW dat=http://10.0.2.2:8081/MyAPPStore/apk/Teflouki.apk typ=application/vnd.android.package-archive flg=0x10000000 }

提前致谢

如果应用程序在市场上不可用，这将无济于事，但如果是：

Uri marketUri = Uri.parse("market://search?q=pname:com.appmaker.tefloukipackage");
Intent marketIntent = new Intent(Intent.ACTION_VIEW, marketUri);
try {
    context.startActivity(marketIntent);
} catch (ActivityNotFoundException ex) {
    showAlertDialog(context, "Error", "Could not launch the market application.", true, null);
}
