"Notification" blocking notification tips for specific apps

property settings for accept notification

@Override        publicvoidsetNotificationsEnabledForPackageintboolean enabled) {            checkCallerIsSystem();            setNotificationsEnabledForPackageImpl(pkg, uid, enabled);        }

Path to Appopsmanager: Frameworks/base/core/java/android/app/appopsmanager.java

public static final int op_post_notification = 11;
UID = App.uid
pkg = App.packagename;
mode = enabled? AppOpsManager.MODE_ALLOWED:AppOpsManager.MODE_IGNORED

See which locations in your code call the Setnotificationsenabledforpackageimpl method

There are two other places to rewrite and implement the method.

Specific resolution steps

When you need to block all app notifications with no exceptions
In Appopsmanager, there are default values for many of the app's settings, compared to the 12th one is the default to the app's notification on or off, Appopsservice in the Checkoperation method is judged, when the OP is empty, Returns the default mode. So the original mode_allowed changed to Mode_ignored after the compilation frameworks/base after the push into the phone restart will find all apps are blocked notice no exception. When a specific app needs to turn on notifications, we can make changes in checkoperation.

   @Override     Public int checkoperation(intCodeintUID, String packagename) {verifyincominguid (UID); VERIFYINCOMINGOP (code);synchronized( This) {if(isoprestricted (UID, Code, PackageName)) {returnappopsmanager.mode_ignored; } op op = getoplocked (Appopsmanager.optoswitch (code), UID, PackageName,false);if(OP = =NULL) {returnAppopsmanager.optodefaultmode (code); }returnOp.mode; }}

In the checkoperation to judge the need to determine the code value, otherwise prone to click Restart Status, modified code as follows.

 Public int checkoperation(intCodeintUID, String packagename) {verifyincominguid (UID); VERIFYINCOMINGOP (code);synchronized( This) {//chenzilong Add for ZELY-41 block app notifications 20160331 start         if(Code = = appopsmanager.op_post_notification) {if((Packagename.equals ("Com.advan.advanstore")|| Packagename.equals ("Com.stkj.android.freeshare"))){returnappopsmanager.mode_allowed; }Else{returnappopsmanager.mode_ignored; }         }//Chenzilong add for ZELY-41 block app notifications 20160331 end            if(isoprestricted (UID, Code, PackageName)) {returnappopsmanager.mode_ignored; } op op = getoplocked (Appopsmanager.optoswitch (code), UID, PackageName,false);if(OP = =NULL) {returnAppopsmanager.optodefaultmode (code); }returnOp.mode; }

The result of the final implementation
