YYHD-工作中一些总结(4)

1.可以更新内存的Code

//change so memory data
int test[]={0xE3A0045D,0xE2800973,0xE2800E87,0xE2800005};
int *temp=(int *)(baseA+0xe22e90);
size_t pagesize = sysconf(_SC_PAGESIZE);
//  Calculate start and end addresses for the write.
uintptr_t start = (uintptr_t) temp ;
uintptr_t end = start + 1024;
//  Calculate start of page for mprotect.
uintptr_t pagestart = start & -pagesize;
if( !mprotect((void *) pagestart, end - pagestart,PROT_READ | PROT_WRITE | PROT_EXEC) ) {
for(int i=0; i<4; i++){
temp[i]=test[i];
//  LogD("my_<%s>,  data = %x",__FUNCTION__, temp[i]);
}
}

#define GETLR(store_lr)	\
__asm__ __volatile__(	\
"mov %0, lr\n\t"	\
:	"=r"(store_lr)	\
)

unsigned lr;
GETLR(lr);

const-string v0, "hook_log"
invoke-static {v0, p0}, Landroid/util/Log;->i(Ljava/lang/String;Ljava/lang/String;)I

void keepSoData(){
FILE *pFile=fopen(SoPath,"r"); //获取文件的指针
if(pFile==NULL){
__android_log_print(ANDROID_LOG_INFO, "native_hook__dump",
"SoPath is null");
return ;
}
char *pBuf;  //定义文件指针
fseek(pFile,0,SEEK_END); //把指针移动到文件的结尾 ，获取文件长度
int len=ftell(pFile); //获取文件长度
pBuf=(char *)malloc(len+1);           //new char[len+1]; //定义数组长度
memset(pBuf,0,len+1);
rewind(pFile); //把指针移动到文件开头 因为我们一开始把指针移动到结尾，如果不移动回来 会出错
fread(pBuf,len,1,pFile); //读文件
pBuf[len]=0; //把读到的文件最后一位 写为0 要不然系统会一直寻找到0后才结束
//显示读到的数据
fclose(pFile); // 关闭文件
FILE *fp;  // 定义一个文件指针fp
fp = fopen("/sdcard/dump_xqm.so", "wb");  // 以二进制可写方式打开stu.dat文件
if(fp==NULL){
__android_log_print(ANDROID_LOG_INFO, "native_hook__dump",
"SoPath is null");
return;
}
int i=0;
fwrite (pBuf , sizeof(char), len, fp);
fclose (fp);
free(pBuf);
}
public static void test(){
Exception e = new Exception("this is a log");
StackTraceElement[]  elements=e.getStackTrace();
StringBuilder sb=new StringBuilder();
for(int i=0; i

2.AndroidStudio 多渠道配置

apply plugin: 'com.android.application'

android {
signingConfigs {
SignConfig {
keyAlias 'iplay'
keyPassword 'passwd11'
storeFile file('release.keystore')
storePassword 'passwd11'
}
}

compileSdkVersion 23
buildToolsVersion '26.0.2'
defaultConfig {
applicationId "com.gameassist.plugin.wedo1.DeathMoto4"
minSdkVersion 15
targetSdkVersion 23
versionCode 1
versionName "1.0.1"
}
buildTypes {
release {
minifyEnabled true
proguardFiles 'proguard-rules.pro'
signingConfig signingConfigs.SignConfig
manifestPlaceholders = [mylabel: "暴力摩托4-release"]
}

debug {
manifestPlaceholders = [mylabel: "暴力摩托4-debug"]
}
}

flavorDimensions "default"
productFlavors {
disheng {
applicationId "com.gameassist.plugin.wedo1.DeathMoto4.disheng"
dimension "default"
}
}

android.applicationVariants.all { variant ->
variant.outputs.all {
outputFileName = "plugins-${variant.flavorName}-${variant.buildType.name}-v${variant.versionCode}-暴力摩托4.apk".toLowerCase()
}
}

}

repositories {
flatDir {
dirs 'libs'
}
}

dependencies {
compile project(':jni')
provided files('libs/pluginInterface.jar')
compile(name: 'frank-c-release', ext: 'aar')
// compile 'com.yyhd.mini.program.frank:franksdk:1.0.2'
}
