问题描述
我已经徒劳地寻找广泛找到没有生根我的Android手机来访问数据库的方法。我不想用AVD，因为它是非常缓慢的。但为了看到我在做什么，我需要从PC或手机上访问我的应用.db文件以某种方式。
I've already vainly searched extensively to find a method to access db without rooting my android phone. I don't want to use AVD as it's very slow. But in order to see what I'm doing I need to access my app .db file from PC or phone in someway.
/data/data//databases/.db没有真正的设备。
/data/data//databases/.db doesn't work for real devices.
所以，请建议我一些方法，通过它我可以看到我的数据库。
So, please suggest me some method by which I can see my database.
推荐答案
只需添加code在特定的情况下应用程序将数据库拷贝到SD卡，这将是乌拉圭回合的DB /数据副本而不是实际的DB 。从SD卡可以随时访问数据库。
这是围绕工作，但它为我工作。
Just add code in your application on specific event it will copy the DB into SD card, it will be copy of ur DB/data not actual DB. From SD card you can always access the DB.this is the work around but it works for me.
下面是code
try {
File sd = Environment.getExternalStorageDirectory();
File data = Environment.getDataDirectory();
if (sd.canWrite()) {
String currentDBPath = "data/"+sPackageName+"/databases/"+sDBName;
String backupDBPath = "/.appname-external-data-cache/"+sDBName; //"{database name}";
File dir = new File(sd,backupDBPath.replace(sDBName,""));
if(dir.mkdir()) {
}
File currentDB = new File(data, currentDBPath);
File backupDB = new File(sd, backupDBPath);
if (currentDB.exists()) {
FileChannel src = new FileInputStream(currentDB).getChannel();
FileChannel dst = new FileOutputStream(backupDB).getChannel();
dst.transferFrom(src, 0, src.size());
src.close();
dst.close();
}
}
} catch (Exception e) {
}
