Android-Implementation of Automatic phone Suspension

Android-Implementation of Automatic phone Suspension
 

Through the two blog posts "Android-AIDL summary" and "Android-AIDL in-depth", I believe you have a certain understanding of Android AIDL. below, we can use Android AIDL to enable automatic phone suspension.

1. Prepare the AIDL File

The AIDL files for hanging up the phone are all Android files. We can find these two files from the Android source code: NeighboringCellInfo. aidl and ITelephony. aidl.

I put NeighboringCellInfo. aidl In the android. telephony package of the project, and put ITelephony. aidl in the com. android. internal. telephony package.

The content of NeighboringCellInfo. aid is as follows:

The specific content of ITelephony. aidl is as follows:

   getNeighboringCellInfo();     int getCallState();     int getDataActivity();     int getDataState();    /**     * Returns the current active phone type as integer.     * Returns TelephonyManager.PHONE_TYPE_CDMA if RILConstants.CDMA_PHONE     * and TelephonyManager.PHONE_TYPE_GSM if RILConstants.GSM_PHONE     */    int getActivePhoneType();    /**     * Returns the CDMA ERI icon index to display     */    int getCdmaEriIconIndex();    /**     * Returns the CDMA ERI icon mode,     * 0 - ON     * 1 - FLASHING     */    int getCdmaEriIconMode();    /**     * Returns the CDMA ERI text,     */    String getCdmaEriText();    /**     * Returns true if CDMA provisioning needs to run.     */    boolean getCdmaNeedsProvisioning();    /**      * Returns the unread count of voicemails      */    int getVoiceMessageCount();    /**      * Returns the network type      */    int getNetworkType();        /**     * Return true if an ICC card is present     */    boolean hasIccCard();}
 

After the file is prepared, the same package as the two files is automatically generated under the project's gen directory, and the ITelephony. java file is automatically generated.

 

For example:

2. Create a PhoneUtils class and write a method endCall ()

This method is the method for hanging up the phone. The specific implementation is as follows:

 

// Hang up the public void endCall (String incomingNumber) {try {Class
 Clazz = Class. forName (android. OS. serviceManager); Method method = clazz. getMethod (getService, String. class); IBinder ibinder = (IBinder) method. invoke (null, Context. TELEPHONY_SERVICE); ITelephony iTelephony = ITelephony. stub. asInterface (ibinder); iTelephony. endCall ();} catch (Exception e) {e. printStrackTrace ();}}

3. Registration permission

Do not forget to register permissions in the AndroidManifest. xml file.
