I’m looking for a programmatic way to set-up http proxy settings for android handsets.

I’m looking for a programmatic way to set-up http proxy settings for android handsets. I’ve tried using android.provider.Settings.System.putString() to set System.HTTP_PROXY, but my call fails (I’m using a 2.2 emulator image at the moment). My code looks like:

if (System.putString(getContentResolver(), System.HTTP_PROXY, "10.10.2.1:8080")) {
    tv.append("put for HTTP_PROXY succeeded.\n");
}
else {
    tv.append("put for HTTP_PROXY failed.\n");
}

I’ve also added to my android manifest:

<uses-permission android:name="android.permission.WRITE_SETTINGS" />
<uses-permission android:name="android.permission.WRITE_SECURE_SETTINGS" />

..although it’s not clear from the docs which permission, if any, is required.

I’m familiar with this SO thread, but the technique there requires manual adb commands, which require the SDK tools and (possibly) a rooted phone.

Is there a way to accomplish this? Ideally, I’d like away to set an http proxy that will be used for both data and wifi connections.

    It’s not possible to do this as a 3rd-party app. You get this message:

    12-07 12:39:37.736: W/PackageManager(85): Not granting permission android.permission.WRITE_SECURE_SETTINGS to package com.mgranja.xxxxxxx (protectionLevel=3 flags=0xbe46)

    Only apps that are signed with the same key as system apps can get this permission (i.e.: if you cook your own rom, you could add that funcionality)

    More info about permission levels on this question, specially adamk’s answer.

    Why are these permissions being refused?
