问题 As you can notice from title, I have a problem with writing file to sdcard in Android. I've checked this question but it didn't help me. I want to write file that will be in public space on sdcard so that any other app could read it. First, I check if sdcard is mounted: Environment.getExternalStorageState(); Then, I run this code: File baseDir = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS); baseDir.mkdirs(); File file = new File(baseDir, "file.txt"); try {

Signing my android application as system app In my company, we would want total control for battery consumption in the field, using only 2g and gps could drain the battery awfully fast. What we decided is that we need to have root access to the mobile phone, So that when phone is idle, we would turn off those needless battery consumption. And also we would not allow users to uninstall it and clear data to it. My Question is : Where do I get these signature key? Is it going to like a root access If ever I successfully managed to sign it? What is the difference between Root vs Signed with key?

I've been trying to encrypt files and write those files back on to the same place. But I got the error message saying "java.io.FileNotFoundException: /storage/emulated/0/New file.txt: open failed: EACCES (Permission denied)". My Manifest file is this <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.example.tdk.mytestapplication2"> <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" /> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/> <application android:allowBackup="true" I think I have provided correct permission

I've done both, if I'm not doing it wrong. And I'm running it on my phone, not the emulator. I've tried both with and without the intent-filters. Here are the codes: Manifest:

How to find required Android Marshmallow runtime permissions in code?

问题 I'm preparing my app to target Android 6.0 Marshmallow. When setting the target api to 23, the app immediately crashes upon launch. There is no useful information in the logcat output. (It gives a "Requested window does not exist" IllegalStateException, but still, nothing actually useful like class name or line number.) This is fine (not really), I eventually narrowed it down to my launch activity where I get the user's device IMEI code (TelephonyManager.getDeviceId()). There needs to be a
