android9.0中怎么添加默認(rèn)apk權(quán)限

android9.0中怎么添加默認(rèn)apk權(quán)限？相信很多沒(méi)有經(jīng)驗(yàn)的人對(duì)此束手無(wú)策，為此本文總結(jié)了問(wèn)題出現(xiàn)的原因和解決方法，通過(guò)這篇文章希望你能解決這個(gè)問(wèn)題。

1.默認(rèn)賦予全部權(quán)限:
安卓動(dòng)態(tài)要求用戶允許添加權(quán)限，直接將如下代碼中的final boolean grantPermissions = (args.installFlags
& PackageManager.INSTALL_GRANT_RUNTIME_PERMISSIONS) != 0;改為final boolean grantPermissions=true便可。

文件路徑: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;
                        */
                        //直接將grantPermissions該為true便可
                        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.根據(jù)包名賦予權(quán)限：

     }

3.通過(guò)default-permissions-google.xml的方式
該文件編譯的時(shí)候要編譯到/system/etc/default-permissions/default-permissions-google.xml中。
可以使用Android.mk的PRODUCT_COPY_FILES方式拷貝。
關(guān)于default-permissions-google.xml相關(guān)的可以參考谷歌https://source.android.google.cn/devices/tech/config/perms-whitelist
