hello everyone i am new in android. My project is a security purpose i want to lock android apps with my lock screen activity (like when user click on gallery then my lock screen comes). i have seen many apps in Play Store like this but i failed to find the code on google. please help me to make this.
I want to build a simple application that records audio files and then compares voices in two audio files in android.I want to record my voice and save them as wav/mp3 files in my device. after that on speaking if voice gets matched with the existing files then it must execute the task. For this i have read every single article and code at Google provided by for similar purpos using FFT, like in shazam and sound hound. but i don’t understand a bit of it that how I can use FFT in my simple application just to find if voice and content of one audio file is similar to second one in Android. I just want a sample application that matches if the voice in the first audio file is identical to the second audio file. I do understand this is a non trivial issue and it seems like there are a lot of articles providing help related to this work but i want a specific help relating to my project in android. i find no way that how can i implement FFt after recording the audio file and how for comparison, in ANDROID. During my research i found a light frame work called musicg( https://code.google.com/p/musicg/ ) and started working with it but the issue with this library is that it does not work in android Jellybean. Please help me by providing some sample projects related to this
I'm currently in the process of designing an app, but need to know if this is possible first. I want to design the app to be able to reject a call before it gets as far as notifying the phones owner (through ringing) or even on the screen. It would essentially just be blocking a phone number, but there is more to this that I can't discuss yet. This is in no way looking to be malicious. If this possible? and if so, are there sample codes to this type of situation?
I would very much like to get into Android development but am mostly familiar with Visual Studio as that is the IDE we used at university. Is it possible to use Visual Studio to develop Android applications or should I go open source? If open source, which one is best? NetBeans?
