1. Give all permissions by default:
Android dynamically requires users to allow them to add permissions, and directly change final boolean grantPermissions = (args. installFlags) in the following code
&
PackageManager.INSTALL_GRANT_RUNTIME_PERMISSIONS)! = 0; Change to final boolean grantPermissions=true.
File path: framework\ base\ services\ core\ java\ com\ android\ server\ pm\ PackageManagerService. java
case POST_INSTALL: {
if (DEBUG_INSTALL) Log.v(TAG, "Handling post-install for " + msg.arg1);
PostInstallData data = mRunningInstalls.get(msg.arg1);
final boolean didRestore = (msg.arg2 != 0);
mRunningInstalls.delete(msg.arg1);
if (data != null) {
InstallArgs args = data.args;
PackageInstalledInfo parentRes = data.res;
/*final boolean grantPermissions = (args.installFlags
& PackageManager.INSTALL_GRANT_RUNTIME_PERMISSIONS) != 0;
*/
// Directly put grantPermissions This is true You can
final boolean grantPermissions = true;
final boolean killApp = (args.installFlags
& PackageManager.INSTALL_DONT_KILL_APP) == 0;
final boolean virtualPreload = ((args.installFlags
& PackageManager.INSTALL_VIRTUAL_PRELOAD) != 0);
final String[] grantedPermissions = args.installGrantPermissions;
// Handle the parent package
handlePackagePostInstall(parentRes, grantPermissions, killApp,
virtualPreload, grantedPermissions, didRestore,
args.installerPackageName, args.observer);
// Handle the child packages
final int childCount = (parentRes.addedChildPackages != null)
? parentRes.addedChildPackages.size() : 0;
for (int i = 0; i < childCount; i++) {
PackageInstalledInfo childRes = parentRes.addedChildPackages.valueAt(i);
handlePackagePostInstall(childRes, grantPermissions, killApp,
virtualPreload, grantedPermissions, false /*didRestore*/,
args.installerPackageName, args.observer);
}
// Log tracing if needed
if (args.traceMethod != null) {
Trace.asyncTraceEnd(TRACE_TAG_PACKAGE_MANAGER, args.traceMethod,
args.traceCookie);
}
} else {
Slog.e(TAG, "Bogus post-install token " + msg.arg1);
}
Trace.asyncTraceEnd(TRACE_TAG_PACKAGE_MANAGER, "postInstall", msg.arg1);
} break;
2. Assign permissions based on package name:
