File Paths outside of the App's private directories in Android Q and above useless. Andrew Andrew 4, 2 2 gold badges 10 10 silver badges 21 21 bronze badges. Question, how do I persist where the file location is that the user selected for the first time?
I don't want to ask the user everytime, if I already downloaded it I just want to pull it from where the user first told me where to store it. The last link shows you how to take permissions that survive a device restart.
If other App's don't need to access the files you are downloading then it would be better to store them in your App's private directory instead which is much simpler as it does not require permissions — Andrew. Right, but I would like to use the DownloadManager to download the files I need and it cannot take in the location of the apps private directory for the destination will throw a SecurityException.

It is not unusual for Android smartphone users to be the target of malware, which is hardly surprising given that there are more than 2.
Cybercriminals will always follow the money, and more users mean more opportunity to infect. I recently wrote about the Joker malware for example, and that wasn't funny in any sense of the word. With 45, Android devices already infected, a total that increases every day, the unremovable malware can even "survive" a factory reset. According to Symantec security researchers, the Xhelper Android Trojan is not only stealthy but also prolific.
Will it delete all of my downloads? Improve this question. Dan Hulme Add a comment. Active Oldest Votes. Device: Nexus 6 Android Version: 5. Improve this answer.
Bodmas Bodmas In addition, Google Play Store is recommended as the safe place to choose apps from. Unfortunately, following these rules are not always enough.
From time to time, the Google Play Store lets some insecure apps slip through. A perfect example is Joker malware , which distributed itself via 24 since-removed apps on Google Play Store and affected over half a million devices in 37 countries.
The short answer is yes and no. Android operating system is definitely the most targeted one by cyber criminals speaking of mobile systems , but it is still a secure system. Here is a quick fact sheet to help you understand whether your security is at risk. Malicious software tends to operate silently to avoid quick identification and removal.

Svpeng virus is Android ransomware that was introduced in However, it seems that it is still active — in , smartphone users are still stuck on this virus which can cause severe problems on their phones and tablets. What does this malware cause? In reality, people who are working behind Svpeng ransomware do not have any connections to the FBI.
They are seeking just to trick their victims into paying the fake ransom. Please, do NOT fall for these claims. You need to remove Svpeng from the system by resetting your device to factory settings. Mazar malware is not a traditional version of an Android virus. This threat spreads via text messages that are filled with infected links.
Once the victim clicks such a seemingly legitimate link, the OS gets infected with the malicious software that starts running dangerous activities behind your back. Typically, it starts monitoring the phone or tablet, changes its settings according to its needs, sends SMS to premium numbers, and initiates illegal connections via the Internet. Those who are connected to it are granted administrator rights, so they can do whatever they want.

Smart cars-hacking malware was introduced by virus researchers at the end of November According to the company, which is known as Promon, it was used by them to hack into the official application of Tesla that allows finding the car, opening its doors, and starting the engine. To perform these commands, Android malware modifies the source code of the official Tesla app at first.
Then, it shares the victim's username and password with the attackers and helps them steal the car. However, the virus, which Promon researchers tested, does not rely on any security vulnerabilities of the Tesla app. According to the company, it has to be installed manually with the help of social engineering and similar techniques.
Ghost Push virus is a notorious malware capable of infecting all Android devices using versions below Nougat V7. The malicious actor functions as a rootkit — it is capable of performing various malicious activities without users' permission. For example, the most prevalent symptom of the infection is downloading and installing other malicious applications and spamming ads non-stop.
Unfortunately, getting rid of Ghost Push is almost impossible. Even factory reset does not do the job, and reflashing firmware would be the only choice for users. However, the good news is that those who are using Nougat, Oreo, and Pie should feel relatively safe, as those versions of the OS are protected from this type of malware. Nevertheless, it does not mean that hackers will not create new variants that would defeat protection measures in the latest versions of Android.
After the infection process is complete, the malware roots the device and enables full access to install more malicious elements. Such activity is done for the sole purpose of stealing your personal information, such as login data to banking accounts. Interestingly, Ghost Push virus , which hit the stage last year, provided a foundation for the current malware. Needless to say, the improved version is much more treacherous.
HummingWhale virus — this malicious virus is an updated copy of HummingBad malware which is known for its massive attacks against smartphone users.
Back in [15] , this virus managed to wreak havoc on approximately 10 million Android devices. Recently, HummingBad appeared in a new form and a new name, and this time it is dubbed HummingWhale malware.

Once the user closed an ad, the malware uploaded already installed the shady program to the virtual machine to create a fake referrer ID used to generate revenue. HummingBad virus. First discovered in February , malware has already infected more than 10 million Android users.
In January , the malware was spotted actively spreading again on the Google Play store as HummingWhale application.
Then, it starts delivering misleading ads and displaying alerts about necessary system updates. When users click on these advertisements, developers of the application generate revenue. Lockdroid ransomware, also known as Android. The virus uses social engineering techniques to get the admin rights of the infected device. It aims to achieve this goal by using a fake package installation. As soon as the installation is completed, Lockdroid virus gets full access to the device and encrypts data.
What is more, it can change the PIN and lock the device. In this way, malware elimination might become difficult. It uses the clickjacking technique and attacks smartphones and tablets with Android 5. According to Google [16] , this malicious app cannot be downloaded from the Google Play Store.
GhostCtrl virus exploits a vulnerability to help its owners to get control over the device. It showed up in the middle of when it was found attacking Israeli hospitals, but it is not considered a new virus. However, according to some of the security experts, malware is not going to stop — soon, it can become a ransomware-type threat as this virus has also been found to have some locking capability as well. It spreads, presenting itself as a legitimate app, such as WhatsApp and Pokemon Go.
Once inside the system, GhostCtrl malware drops a malicious Android application package APK and opens the backdoor of the system to provide full access to the victim's personal information, videos and audios. It can also reset passwords and call or send texts to the victim's contacts. There are multiple fake anti-virus engines that are, in fact, malware themselves, while others are entirely ineffective.
Make sure you pick a reputable anti-virus tool that does not spam you with bogus alerts. In July , security experts discovered an updated and improved variant of Svpeng attacking banking app users in 23 countries and dubbed it Invisible Man. Fortunately, malware hasn't made it to the Google Play Store. However, when users install this malicious app, they give administrator rights to the device.
As a result, cybercriminals can control it via the Command and Control server. The malicious program works as a key-logger and collects credentials when a user logs in to the bank via a mobile app.
