Many of the Android code is not all people, we know! Like a little taller on the dot ad implanted. But in order to let the user mobile phone installed on the anti-virus software does not detect ads,We need to take the following non-normal means, as follows:When we write the Android app code, we will put all the code in the SRC directory, but when we package the Android

Then the background thread checks if the reference is cleared, and if not, the GC is called.
If the reference is still not cleared, dump the heap

AndroidIn fact, the code of the headset detection is rarely changed.
This is because there are few documents.
It took nearly two months.
The driver has three implementation versions:
First, drivers/Char/micco_hsdetect.cIt reports the status to the user space through kobject_uevent.
Second: Drivers/input/keyboard/micco_keys.cIt reports events to the user space through input_report_switch.
Third: Drivers/switch/switch_micco.cRegistered a switch_dev, whi
The error prompt Method for Automatic code detection of Android Studio is a bit odd, which is very different from that of Eclipse. Eclipse detects that a resource file cannot be found or is incorrect, this method is not required for Android Studio, so it is estimated that the error message is not found at the beginning for half a day? This error message is direct
The principle of app upgrade is very simple, get the latest version of the service side of the release information, and its own version of the information, if its own version is low, you can prompt users to download the new version. For Android apps, version information is primarily stored in the Androidmanifest.xml file: Android:versioncode represents the version number, which is an integer, Android:versionname represents the version name and a stri

Android EditText input detection, androidedittext
A Story occurred when a function was recently developed. The plot is as follows:
The function is not complex, and an EditText is needed to obtain the user input information. Therefore, I made a Dialog to display my input interface (the Code is as follows ):
mAlertDialog = new AlertDialog.Builder(this)//, android.R.style.Theme_Holo_Light .setI
