Looking at your screenshot, I think you are using screen filtering apps like Twilight, f.lux, CF.lumen and bluelight filter. Try to force stop/uninstall/disable the screen filtering app and it will work again. If you are not using any filtering app, try looking for your installed apps that have overlay capability, apps that can show their contents over ...

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 ...

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... ...

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 ...

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 ...

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.

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 ...

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 ...

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 ...

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 ...

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 ...

Folks consider adb sideload <ZIP> when they have a ready to flash .zip file. The command is mostly used when booted into Recovery mode. Fastboot on the other hand often deals with per partition flashing at a time. E.g. fastboot flash recovery <IMG> -- only flashes Recovery partition and not all the relevant partitions for ROM installation. ADB ...

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 ...

Use ADB to install the applications. Install the Android 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

Had the same problem, plus the device was shown with a yellow exclamation mark in the device manager but only when in recovery mode. Solution was to install the Google USB drivers for this device again: Google and Download "Google USB Driver" Open device manager Right click device Update Driver Software Select "Browse my Computer ..." Select "Let me pick .....

It's important to note that Android apps don't get installed in the same way as on Windows or on GNU/Linux systems. The app runs entirely from the APK file. Installing an app for the first time includes the following steps: Download the APK to the storage. All apps' APK files get downloaded to the same location. Create a user ID for the new app. Each app in ...

You should download the Android SDK and use it to install the Android SDK Tools, which includes adb and fastboot.

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.


3

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 ...

adb sideload does not transfer the file to the sdcard permanently. To sideload correctly, you need to pick that option from the recovery first and then when the phone is waiting for the sideload type, adb sideload <PACKAGE> If you want to push the file to the phone's sdcard, you could try, adb push <PACKAGE> /sdcard/ That should copy the file ...

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 ...

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 ...

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 ...

Eventually, I found a workaround (which is not a fix but it allowed me to continue the installation). Since my device was detected in discovery, I did not used sideload. I just pushed the image to the sdcard with: adb push xxxxx.zip /sdcard/ and then I installed the image from the sdcard directly in TWRP.

Such unlock apps aren't official. They employ various methods of unlocking based on the information they gather from the app installed and querying from supposedly authentic database of unlock codes. I have personally used an unlock service for an iPhone which was locked to a carrier. I needed to supply device information and within a few hours they ...

The whole answer relies on the fact that when this query is made (requires adb) : adb shell pm list packages -3 -i the installer for an app is listed in the output next to app's package name. We can filter the installer names in that output to single out apps not installed from Play Store. Note: if you've a rooted Android OS, you may check /data/system/...

You can't install a ROM using adb install, just like you can't install a fresh Ubuntu system with apt-get. You use fastboot to install new ROMs, when the device is in fastboot mode. Instructions are different for each device, and the ROM you downloaded should come with them. Regardless, from the symptoms you describe, it doesn't sound like installing a new ...

Download/get the .apk file of desired application. (Example: MoboPlayer from this link.) Pass it to the android device. Use any file explorer to open this .apk file. Install the application.
