Fix stub strings

In commit 8d4c407, native Magisk always launches an activity for
communicating with Magisk Manager. While this works extremely well,
since it also workaround stupid OEMs that blocks broadcasts, it has a
problem: launching an activity will claim the focus of the device,
which could be super annoying in some circumstances.

This commit adds a new feature to run a broadcast test on boot complete.
If Magisk Manager successfully receives the broadcast, it will toggle
a setting in magiskd so all future su loggings and notifies will always
use broadcasts instead of launching activities.

Fix #1412

 # Magisk
 
-## How to build Magisk
+[Downloads](https://github.com/topjohnwu/Magisk/releases) \| [Documentation](https://topjohnwu.github.io/Magisk/) \| [XDA Thread](https://forum.xda-developers.com/apps/magisk/official-magisk-v7-universal-systemless-t3473445)
 
-#### Building has been tested on 3 major platforms: macOS, Ubuntu, Windows 10
+## Introduction
 
-### Environment Requirements
+Magisk is a suite of open source tools for customizing Android, supporting devices higher than Android 4.2 (API 17). It covers the fundamental parts for Android customization: root, boot scripts, SELinux patches, AVB2.0 / dm-verity / forceencrypt removals etc.
 
-1. Python 3.5+: run `build.py` script
-2. Java Development Kit (JDK) 8: Compile Magisk Manager and sign zips
-3. Latest Android SDK: `ANDROID_HOME` environment variable should point to the Android SDK folder
-4. Android NDK: Install NDK along with SDK (`$ANDROID_HOME/ndk-bundle`), or specify custom path `ANDROID_NDK`
-5. (Windows Only) Python package Colorama: Install with `pip install colorama`, used for ANSI color codes
+Furthermore, Magisk provides a **Systemless Interface** to alter the system (or vendor) arbitrarily while the actual partitions stay completely intact. With its systemless nature along with several other hacks, Magisk can hide modifications from nearly any system integrity verifications used in banking apps, corporation monitoring apps, game cheat detections, and most importantly [Google's SafetyNet API](https://developer.android.com/training/safetynet/index.html).
 
-### Instructions and Notes
-1. Magisk can be built with the latest NDK (r16 as of writing), however binaries released officially will be built with NDK r10e due to ELF incompatibilities with the binaries built from the newer NDKs.
-2. The easiest way to setup the environment is by importing the folder as an Android Studio project. The IDE will download required components and construct the environment for you. You still have to set the `ANDROID_HOME` environment variable to point to the SDK path.
-3. Run `build.py` with argument `-h` to see the built-in help message. The `-h` option also works for each supported actions, e.g. `./build.py binary -h`
-4. Build everything with `build.py`, don't directly call `gradlew` or `ndk-build`, since most requires special setup / dependencies.
-5. By default, `build.py` will build binaries and Magisk Manager in debug mode. If you want to build Magisk Manager in release mode (through the flag `--release`), you will need to place a Java Keystore file at `release_signature.jks` to sign Magisk Manager's APK. For more information, check out [Google's Official Documentation](https://developer.android.com/studio/publish/app-signing.html#signing-manually).
+## Bug Reports
 
+**Make sure to install the latest [Canary Build](https://forum.xda-developers.com/apps/magisk/dev-magisk-canary-channel-bleeding-edge-t3839337) before reporting any bugs!** **DO NOT** report bugs that is already fixed upstream. Follow the instructions in the [Canary Channel XDA Thread](https://forum.xda-developers.com/apps/magisk/dev-magisk-canary-channel-bleeding-edge-t3839337), and report a bug either by opening an issue on GitHub or directly in the thread.
+
+## Building Environment Requirements
+
+-  Python 3: run `build.py` script
+-  Java Development Kit (JDK) 8: Compile Magisk Manager and sign zips
+-  Latest Android SDK: set `ANDROID_HOME` environment variable to the path to Android SDK
+-  Android NDK: Install NDK along with SDK (`$ANDROID_HOME/ndk-bundle`), or optionally specify a custom path `ANDROID_NDK_HOME`
+-  (Windows Only) Python package Colorama: Install with `pip install colorama`, used for ANSI color codes
+
+## Building Notes and Instructions
+
+-  Clone sources with submodules: `git clone --recurse-submodules https://github.com/topjohnwu/Magisk.git`
+-  Building is supported on macOS, Linux, and Windows. Official releases are built and tested with [FrankeNDK](https://github.com/topjohnwu/FrankeNDK); point `ANDROID_NDK_HOME` to FrankeNDK if you want to use it for compiling.
+-  Set configurations in `config.prop`. A sample file `config.prop.sample` is provided as an example.
+-  Run `build.py` with argument `-h` to see the built-in help message. The `-h` option also works for each supported actions, e.g. `./build.py binary -h`
+-  By default, `build.py` build binaries and Magisk Manager in debug mode. If you want to build Magisk Manager in release mode (via the `-r, --release` flag), you need a Java Keystore file `release-key.jks` (only `JKS` format is supported) to sign APKs and zips. For more information, check out [Google's Official Documentation](https://developer.android.com/studio/publish/app-signing.html#signing-manually).
+
+## Translations
+
+Default string resources for Magisk Manager are scattered throughout
+
+- `app/src/main/res/values/strings.xml`
+- `stub/src/main/res/values/strings.xml`
+- `shared/src/main/res/values/strings.xml`
+
+Translate each and place them in the respective locations (`<module>/src/main/res/values-<lang>/strings.xml`).
+
+## Signature Verification
+
+Official release zips and APKs are signed with my personal private key. You can verify the key certificate to make sure the binaries you downloaded are not manipulated in anyway.
+
+``` bash
+# Use the keytool command from JDK to print certificates
+keytool -printcert -jarfile <APK or Magisk zip>
+
+# The output should contain the following signature
+Owner: CN=John Wu, L=Taipei, C=TW
+Issuer: CN=John Wu, L=Taipei, C=TW
