Need help correctly emulating the Samsung Galaxy Nexus with AVD

由 孤街浪徒 提交于 2019-12-04 07:14:09
I'm working to ensure my app is getting tested on ICS properly using the popular Galaxy Nexus as a basis. I'd like to emulate it as faithfully as possible. I've created an AVD with the following parameters (from config.ini). This was mostly created using the GUI (disk.dataPartition.size is a hand-edited param based on other articles I've read). The memory values may be on the low side but that's not causing a problem for me at the moment. Since the device had no external sdcard I've said "no" for hw.sdCard, but I'm clearly not seeing anything in the /mnt/scdcard (same as /sdcard) and cannot

PhoneGap/Cordova BlackBerry FileSystem.root always returns SD card?

由 狂风中的少年 提交于 2019-12-04 03:45:34
I have two applications I'm loading on a BlackBerry, one is a native application, the other is a PhoneGap / Cordova based application. These two applications share a settings file: file:///store/home/user/myfile.txt To access this file via Cordova, I call: fileSystem.root.getFile("home/user/myfile.txt", null, gotFileEntry, fail); However, on some devices fileSystem.root returns the SDCard directory, not the internal memory where the file is stored, so I get a FileNotFound error. I've tried calling fileSystem.root.getParent(gotParent, fail); , hoping to get the root of the filesystem, then get

Android low-level read of SD card greater than 2GB

由 自闭症网瘾萝莉.ら 提交于 2019-12-04 03:25:23
My Android application attempts to read the physical sectors of the SD card by accessing the actual device (in my case, /dev/block/vold/179:1). (this is on a rooted phone, of course) I'm able to open the device as a FileInputStream , and read data from it. However, I can't seem to read it past the 2GB mark (my memory card is 16GB). Is this because Android doesn't support files greater than 2GB? If that's the case, why do functions like position() and skip() accept long arguments?? Does anyone have advice on how to read from the device past 2GB? try create with a native (jni) lib and call _

Android - How to start an application on the /sdcard after boot

由 萝らか妹 提交于 2019-12-04 00:06:16
Is there a way how to start and android application after a boot automatically if it is on the /sdcard ? Ok, probably by BroadcastReceiver . But which action is the right one? ACTION_BOOT_COMPLETED - does not work if it is on the /sdcard (documented) ACTION_MEDIA_MOUNTED - does not work if it is on the /sdcard (which is undocumented) ACTION_EXTERNAL_APPLICATIONS_AVAILABLE - does not work, I do not know why ACTION_USER_PRESENT - does not work if the BroadcastReceiver is registered in AndroidManifest (which is undocumented, but documentation bug has been reported) Thanks Jan Rahul Chaudhary

Android: How to load image into Bitmap

由 允我心安 提交于 2019-12-03 21:36:36
I am able to load a resource image, from drawable folder, into a bitmap and even scale fine, however now I have a need to load an image from any stored on the SD-Card and I can see this will allow me to view and select; startActivityForResult(new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.INTERNAL_CONTENT_URI), 1); However so far I have been unable to find out exactly what data is returned and how to load it into a bitmap. UPDATED: This is now what I got; @Override protected void onActivityResult(int requestCode, int resultCode, Intent intent) { super.onActivityResult
