I have dug around and found a function to copy files, my only issue is I do not know where I insert my directory (I'm moving "/data/data/com.android.providers.contacts/databases/contacts2.db"
to "/sdcard/tpzb/"
)
I would appreciate some help very much. All I need is someone to put "FILE TO COPY DIR"
and "OUTPUT DIR"
in where it goes. I know this is a dumb question but I see many other functions like this, I figure once I see one I will be able to figure it out on my own with out asking. :)
private void moveFile(String inputPath, String inputFile, String outputPath) {
InputStream in = null;
OutputStream out = null;
try {
//create output directory if it doesn't exist
File dir = new File (outputPath);
if (!dir.exists())
{
dir.mkdirs();
}
in = new FileInputStream(inputPath + inputFile);
out = new FileOutputStream(outputPath + inputFile);
byte[] buffer = new byte[1024];
int read;
while ((read = in.read(buffer)) != -1) {
out.write(buffer, 0, read);
}
in.close();
in = null;
// write the output file
out.flush();
out.close();
out = null;
// delete the original file
new File(inputPath + inputFile).delete();
}

使用此code复制文件
另外,请勿忘记在AndroidManifest.xml
文件
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
用法
copyFile("/data/data/com.android.providers.contacts/databases/contacts2.db", Environment.getExternalStorageDirectory().toString() + "/tpzb/");
