嗨朋友感谢以前的回复， 我面临删除缓存和临时文件/文件夹的问题， 我需要的是从一个应用程序清理整个设备临时文件和缓存是我的应用程序 但在这里我能够只清洁我的应用程序缓存，这里是我的代码缓存和临时文件/文件夹删除android

private void mAppMethod(List mApps) {

// TODO Auto-generated method stub

// File f = g

for (int i = 0; i < mApps.size(); i++) {

File dir = new File("/data/data/"+mApps.get(i).getPackageName().concat("/cache"));

Log.e("dir "+dir, "is directory "+dir.isDirectory());

int j = clearCacheFolder(dir, 10);

if (dir!= null && dir.isDirectory())

Log.e("j", "rff "+dir.delete());

System.out.println(j+" rff "+dir.delete());

}

和我清除缓存的方法下

static int clearCacheFolder(final File dir, final int numDays) {

int deletedFiles = 0;

if (dir!= null && dir.isDirectory()) {

// System.out.println("here"+dir.delete());

Log.e("here", "here "+dir.isDirectory());

try {

Log.e("here1", "here1"+dir.listFiles());

for (File child:dir.listFiles()) {

Log.e("here11", "here11");

//first delete subdirectories recursively

if (child.isDirectory()) {

Log.e("here111", "here111");

deletedFiles += clearCacheFolder(child, numDays);

Log.e("here1111", "here1111");

}

Log.e("here11111", "here11111");

//then delete the files and subdirectories in this dir

//only empty directories can be deleted, so subdirs have been done first

if (child.lastModified() < new Date().getTime() - numDays * DateUtils.DAY_IN_MILLIS) {

Log.e("here111111", "here111111");

if (child.delete()) {

Log.e("here1111111", "here1111111");

deletedFiles++;

Log.e("here11111111", "here11111111");

}

}

}

}

catch(Exception e) {

Log.e("TAG", String.format("Failed to clean the cache, error %s", e.getMessage()));

}

}

return deletedFiles;

}

请帮助我怎样才能清除整个装置缓存，这里我是ge拟合每Apps缓存位置即DIR在设备中的所有应用程序的缓存，但是当我要删除它们返回false

请帮助任何帮助是明显的

我能够清除一个应用程序的缓存也就是一个我运行这段代码，但不能用于其他应用提前
