android9.0中怎么添加默认apk权限？相信很多没有经验的人对此束手无策，为此本文总结了问题出现的原因和解决方法，通过这篇文章希望你能解决这个问题。
1.默认赋予全部权限:
安卓动态要求用户允许添加权限，直接将如下代码中的final boolean grantPermissions = (args.installFlags
& PackageManager.INSTALL_GRANT_RUNTIME_PERMISSIONS) != 0;改为final boolean grantPermissions=true便可。
文件路径: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;
*/
//直接将grantPermissions该为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.根据包名赋予权限：
文件路径:framework\base\services\core\java\com\android\server\pm\permission\DefaultPermissionGrantPolicy.java
--- a/frameworks/base/services/core/java/com/android/server/pm/permission/DefaultPermissionGrantPolicy.java

}3.通过default-permissions-google.xml的方式
该文件编译的时候要编译到/system/etc/default-permissions/default-permissions-google.xml中。
可以使用Android.mk的PRODUCT_COPY_FILES方式拷贝。
关于default-permissions-google.xml相关的可以参考谷歌https://source.android.google.cn/devices/tech/config/perms-whitelist
