热修复框架-Tinker安装流程分析

代码tinker 1.9.14.7

TinkerApplication初始化完成之后，接着会在继承DefaultApplicationLike的⼦类中进⾏Tinker初始化：

@Override

public void onBaseContextAttached(Context base) {

ContextAttached(base);

Log.d(TAG, "HotFixApplicationLike onBaseContextAttached");

l(base);//使应⽤⽀持分包

LoadReporter loadReporter = new DefaultLoadReporter(base);

PatchReporter patchReporter = new DefaultPatchReporter(base);

PatchListener patchListener = new DefaultPatchListener(base);

public void install(Intent intentResult, Class serviceClass,

AbstractPatch upgradePatch) {

sInstalled = true;

//将UpgradePatch和DefaultTinkerResultService 组合进TinkerPatchService

chProcessor(upgradePatch, serviceClass);

TinkerLog.i(TAG, "try to install tinker, isEnable: %b, version: %s", isTinkerEnabled(), _VERSION);

if (!isTinkerEnabled()) {

TinkerLog.e(TAG, "tinker is disabled");

return;

}

if (intentResult == null) {

throw new TinkerRuntimeException("intentResult must not be null.");

}

tinkerLoadResult = new TinkerLoadResult();

TinkerLog.i(TAG, "parseTinkerResult loadCode:%d, process name:%s, main process:%b, systemOTA:%b, fingerPrint:%s, oatDir:%s, useInterpretMode:%b",

break;

// _DEX, false);

}

break;

case _LOAD_PATCH_VERSION_RESOURCE_MD5_MISMATCH:

if (resourceFile == null) {

TinkerLog.e(TAG, "resource file md5 mismatch, but patch resource file not found!");

throw new TinkerRuntimeException("resource file md5 mismatch, but patch resource file not found!");

}

I/LoadResult: parseTinkerResult loadCode:-3, process name:sdkdemo, main process:true, systemOTA:false, fingerPrint:Xiaomi/dipper/dipp

loadCode -3 :对应ERROR_LOAD_PATCH_INFO_NOT_EXIST

看看是什么原因set的
