But each time I disconnect the camera, and reconnect it, I have to do it again. Via shell I can remount the root file system r/w mount -o rw,remount -t rootfs rootfs / and

问题 # sqlite3 /data/data/com.moodme.android/databases/moodme sqlite3 /data/data/com.moodme.android/databases/moodme sqlite3: not found 回答1: On the Android emulator, sqlite3 is in /system/xbin . There is no /system/xbin on a Nexus One (Android 2.2). Hence, I suspect that sqlite3 is not installed on the Nexus One. 回答2: As an alternative (may not be secure or even good idea though) you can always upload the sqlite3 binary to /system/bin this worked for me: First lets mount /system/ to allow read

I am trying to use reflexion techniques to get access to NFCExtras : mAdapter = NfcAdapter.getDefaultAdapter(this); try { Class mynfcextras = Class.forName("android.nfc.INfcAdapterExtras"); Method getnfcExtras = mAdapter.getClass().getMethod("getNfcAdapterExtrasInterface"); Object nfcExtras = getnfcExtras
