Before Android 2.1 Program It can only be installed in the body memory (RAM). This feature prevents Android development from some point of view, because Ram has limited space, therefore, this feature limits the size of the application and the functionality of the application. Since Android 2.2, the android system

"Android" Android mobile app data to SDYou can specify it in the application's Menifest file, include the Android:installlocation attribute in the ... >Android:installlocation also has two additional attribute values: "Preferexternal" and "Auto", which, according to the literal meaning, may also understand what it means, or the following:If you define "preferexternal", it means that you require your app to

The example in this article describes how Android saves bitmap objects to an SD card. Share to everyone for your reference. as follows: Bitmap Logobitmap = Bitmapfactory.decoderesource (Mcontext.getresources (), R.drawable.arcnote_logo); Bytearrayoutputstream Logostream = new Bytearrayoutputstream (); Boolean res = logobitmap.compress (bitmap.compressformat

From: http://blog.csdn.net/chthq/article/details/7838033 2. Create a database on the SD card Through the sqliteopenhelper class source code of Android, you can see the getwritabledatabase of the sqliteopenhelper class This interface actually calls the openorcreatedatabase method of context, which does not support database names with paths. That is to say, the da

When Android is developed, you will encounter the following scenarios I want the application to download to the root of the current application, not the SD card This file can then be accessed by the application or other application at any time, with permissions that are read globally File writes can be made using the context's local file output stream at this t

How do you judge a document? You can traverse the database by cursor, comparing the value of the Internal_content_uri field, which is a URI that holds the full path to the multimedia file on the Android phone's SD card. [Java] Copy Code code as follows: Uri Originaluri = MediaStore.Images.Media.EXTERNAL_CONTENT_URI; If the video is MediaStore.Video.M

In the android system, when the SD card is attached to a computer and the recording in the voice memo is deleted manually, the data in the corresponding database also needs to be modified. In this case, you need to listen to the Mount and inherit the BroadcastReceiver class to implement the onRecieve (Context context, Intent inten) method. The Code is as follows:

When developing Android, you may encounter one of the following scenarios: You want to download the application to the root directory of the current application, not the SD card. Then, the file can be accessed by the application or other applications at any time, that is, the file can be read globally. In this case, you can use the local file output stream o

In the Windows Mobile system, you can choose to install the software on the mobile phone memory or memory card during software installation. In the Android system, you can only install the software in the mobile phone memory, it makes the memory of a small mobile phone appear easy.
