Are you using screen filtering apps? because your screenshot looks red-dim. If yes, disable the screen filter app and it will work again. If you are not using any filtering app, try looking for screen-related apps installed on your phone. This kind of problem mostly related to screen-related apps. Try disable them one by one in your Settings ⇒ Apps and find ...

It is difficult to know whether an APK is safe or not. Your best bet is to download from trusted or reputable sources (like Google Play, Amazon, etc). Some (trusted) developers also provide an MD5 (or other message-digest algorithm) hash of their APKs. After your download the APK, you verify if the APK has the same hash. If it does, then it's safe to say ...

If your device allows it (AT&T only recently started producing phones that do) there is a setting which allows you to install non-Market apps. Then you can install APKs from anywhere, assuming you can get them on your device. On my Droid, at least, the setting is at Settings | Applications | Unknown sources.

This question seems to say that it's necessary to root an at&t phone (like the samsung captivate) in order to install apps from unofficial sources. That is not true. While you cannot download apps from the Web, you can install apps through the development tools, or things based on the development tools (like the Sideloader Wonder Machine). My ...

Google introduced an option Verify apps (Disallow or warn before installation of apps that may cause harm) for side-loaded apps when unknown sources is enabled (both settings available in Settings -> Security -> device-administration). You can also use an online virus scanner like Virus Total to check your downloaded .apk file. But this is the same with ...

Usually sideloading is not prevented by the manufacturer, but by the operator. All the tablets I've tried had no operator customizations and supported sideloading. Of course, this depends on your country and operator.

No need to load a custom ROM. You have two paths possible -- You can simply use special software on your PC to sideload apps or you can do some edits to the configuration databases on the phone to bypass the block permanently. This page covers both methods -- http://samsungcaptivate.wikia.com/wiki/How_to_Sideload

You can get the .apk files from developers' sites or other forums like androidfreeware.org and alternative markets like slideme.org. Al Everett's answer above is part of the solution. After changing the settings to enable you to install 3rd party apps, you can either upload / add the APKs of apps that you want on to your SD card and then using a File ...

Grab this .apk file from the XDA forums and sideload it like you would any other app. The instructions state that it will work on unrooted devices, and CNET actually ran an article detailing this a little while back. The original XDA thread is here, the link you need is the one under the QR code (the "APK method"). This particular method will evidently only ...

I don't know that there's a definite way to answer this. It would be almost entirely dependent on how exactly the app was attempting to infect your phone and how successful its attempts were. In the simplest case, maybe the app is sniffing data or something of that sort. For that case, uninstalling would basically remove the threat since the app would be ...

If you are downloading the .apk files from unknown/untrusted sources, there's no easy way to judge. Most Anti-Whatever solutions (anti-virus, anti-malware, etc.) are just ruling by "database entries" (i.e. they have a database of known malware, and check whether the package name matches), or only check requested permissions (and not whether e.g. a SMS app ...

Goal If you have the OTA image downloaded and, as in my case, ended up without success you should be able to adb sideload <filename> it still manually (video here). Problem/Error ... unfortunately the OTA update via adb sideload errors out with: Finding update package... Opening update package... Verifying update package... Installing update... ...

You can create an application for any device that runs the Android OS, this is not restricted to specific device manufacturers. Restrictions in the execution are caused mainly because of the version of the Android OS that runs on the device (the differtent API's) or the difference in hardware capabilities between devices. If you are planning to make an ...

Use slideME. Download the apk from here tp your phone, then install the application from your phone and you can use that to download and buy apps. See this question: Alternative Android App Markets for a list of Market alternative Edit: Don't forget to enable non-market installation in Settings > Applications > Unknown sources

The Android Compatibility Definition Document (direct pdf) says that “Device implementations MUST support the Android Developer Tools provided in the Android SDK.” Any device which isn't “compatible with Android” according to this document isn't going to have the Google services, and in particular would not have the Google Play Store. Such devices do exist, ...

You will need root access on your devices (well, at least on the old one) in order to copy the apps off it. Once rooted, you can use a number of 3rd-party "Backup" apps to save a copy of the apps to your SD Card, copy it to your PC, and then side-load them onto your new phone. The one I use is Titanium Backup. Root your original device. Look at sites ...

Unfortunately the ADBD (adb daemon) is not enabled on any current Google TV hardware, so adb connectivity is not possible via USB, Ethernet, or any other means. However, a few crafty tinkerers from GTVhacker site managed to hack the Logitech Revue unit to enable this functionality. Keep in mind that this is a hardware hack and includes physically opening ...

Use adb to install the applications. Install the adnroid sdk ( https://developer.android.com/sdk/index.html ). Enable usb debugging in settings>applications>development. This process can be done even without enabling side-loading of apps. Open a command prompt window and type: adb install app_name.apk


4

No, or at least not in a way that can't be automated away. Titanium Backup can install apps without the user seeing this prompt, for example. It may require root to do this. Without root, only the system can access the areas needed to install apps. So barring any bugs, apps can only be installed by the system and the system will show the permissions if ...

You can upload the package to a mobile sandbox to see what it's doing. The sandboxes will execute the binary and you can see the execution resutls. This will also work for some formerly unknown malware as it doesn't have to be in some av-database before. Examples for sandboxes are MobileSandbox, CopperDroid, SandDroid, TraceDroid, Joe Sabdox Mobile, ForSafe ...

It seems that this can be done with Aptoide server and the same Android app for client. On server side you just copy all APKs and generate the XML file via Aptoide server script. User then installs this app, adds your repository and downloads/installs the APK.

Once the user allows Unknown Sources, they should pretty much be able to get APK from anywhere... Check this StackOverflow question: Hosting an .apk file on over own site

Turns out I was right to suspect that this has been done before. The fix I was looking for was Super One Click. It has a fix to allow non market apps. I think what it does is to change the config file that the settings dialog ("Allow Non Market Apps") normally sets. My guess its that AT&T just took out the UI for the option. Anyway, works perfectly and ...

You could use other App stores like Amazon App Store or GetJar, but you would also need accounts on those. You can side-load apps via downloading APK files on PC and then installing them from your SD card. Just try opening the APK files with a file manager like ES File Explorer or ASTRO File Manager which would give a option to open it with Package manager ...


3

No. Installing packages is still a privilege reserved to the package manager, which is a system app (i.e. it's inside the ROM), and the package manager doesn't offer an interface to avoid the confirmation dialog. This is by design. That said, if USB debugging is enabled (in the developer options), you can use adb to install an APK file from a PC, with no ...

No. If you don't uninstall the existing app, and you use adb install to install the new APK, the existing app data will be preserved. Note that you can only do this if the package names match and the old and new APKs are signed with the same developer certificate: If the package names don't match, then both versions will be installed side-by-side, and the ...

Sideloaded apps are not linked to Google Play. You will have to update them manually (i.e. sideloading) What you could do is install Titanium Backup (needs root), and use its Attach to Market feature. Another solution would be to use AppBrain instead of Google Play, because AppBrain scans the apps in your phone, and informs you of any updates.

Using the command, adb install -r whatever.apk will install the application in 2nd user of android 5.0.2 . Source

You're better off with Izzy's advise and find and weed out the app trying to install that Clean Master app. Anyhow, there you go with an another solution. When you attempt to sideload an apk using UI or any app that attempts to install an apk and isn't granted the permission android.permission.INSTALL_PACKAGES, Package Installer app comes into action and ...
